Analysis of permanent deformations of flexible airport pavements by Yu T Chou( Book )

4 editions published in 1977 in English and held by 112 WorldCat member libraries worldwide

This study was conducted to investigate the deformation characteristics of component materials in a flexible pavement system subject to moving aircraft loadings, and to attempt to develop a prediction model to estimate permanent deformation. Series of laboratory repeated load tests measuring permanent strain were performed on subgrade soil and untreated granular materials. The results were used as input to a layered elastic computer program to determine the accumulated permanent deformation that occurred in each layer of the pavement. Pavements used in the analysis were full-scale multiple-wheel heavy gear load test sections and pavements designed by using the CBR equation. The permanent deformation occurring in the subgrade soil of many pavements was computed using the linear layered elastic computer program and laboratory repeated load test data. Results of the analysis indicate that the current concept of the control of subgrade rutting in flexible pavements by the limitation of elastic strain is not strictly correct. When subgrade strain is limited, subgrade rutting may not be limited and may not be controlled
Earthquake resistance of earth and rock-fill dams : report 5, permanent displacements of earth embankments by Newmark sliding block analysis by A. G Franklin( Book )

4 editions published in 1977 in English and held by 98 WorldCat member libraries worldwide

In 1965, Newmark described methods for computing permanent displacements of embankments subjected to earthquake loading, and provided a chart for estimating the upper bounds of permanent displacements on the basis of a sliding block model and four earthquake records. Since that time, many additional strong-motion records have been obtained in the western United States, and it was decided to extend the data base for Newmark's chart by making use of these records. For this purpose, a computer program was written to integrate the digitized accelerograms and compute the permanent displacements from the velocity-time history and the resistance coefficients. All records were scaled to 0.5g peak acceleration and 30-in./sec peak velocity, and the resulting scaled permanent displacements are called standardized maximum displacements. A total of 169 horizontal and 10 vertical corrected accelerograms were processed in addition to several synthetic records
Hydraulics and stability of tidal inlets by Francis F Escoffier( Book )

3 editions published between 1977 and 1978 in English and held by 94 WorldCat member libraries worldwide

This report presents a summary of several of the important basic developments pertaining to analysis of the hydraulics and related stability of tidal inlets. The original inlet stability concept proposed by Escoffier is extended in light of recent work. The report also contains brief discussions on tidal inlet characteristics and functional design requirements as well as case studies of selected inlets on the U.S. coasts

An evaluation of expedient methodology for identification of potentially expansive soils by Donald Snethen( Book )

4 editions published in 1977 in English and held by 90 WorldCat member libraries worldwide

This report concludes an evaluation of expedient methodology for identifying and qualitatively classifying potentially expansive soils. Seventeen published techniques used for identification/classification purposes were reviewed and evaluated using data collected from an extensive laboratory testing program. A definition of potential swell that is more consistent with field simulation requirements and more representative of in situ volume change behavior is presented. The results of the evaluation of published techniques reveal that the best techniques and thus the best indicators of potential swell are the liquid limit and plasticity index
Overland flow treatment of wastewater : interim report by Charles A Carlson( Book )

3 editions published in 1974 in English and held by 89 WorldCat member libraries worldwide

Land application has been suggested as an effective, low-cost method for advanced treatment of wastewater from military reservation treatment plants. This study is being conducted to determine the mechanisms involved in wastewater treatment by overland flow so that operational feasibility, design, and performance criteria can be more accurately evaluated. A model 5 ft wide and 20 ft long was prepared with grass sod and a low-permeable Susquehanna clay to a 6-in. depth at a 2% slope. Secondary effluent from a model treatment plant was supplemented with 13.4 mg/l of nitrogen as ammonium nitrate and 0.2 mg/l of cadmium, copper, lead, manganese, nickel, and zinc to simulate average wastewater. The study was conducted for 12 weeks with effluent applied by flooding from the upper end of the slope at 0.5 in./day (6-hr periods) for 4 days per week. The wastewater was generally distributed into 20, 30, and 50% for subflow, evapotranspiration, and runoff, respectively. Analyses showed that 100, 95, 91, and 75% of the ammonium, nitrate, and organic nitrogen and phosphorus, respectively, were retained in the model. The loss of 25% of the applied phosphorus in runoff indicated a need for more surface contact, probably obtainable by increasing the model length. The subflow analyses showed excellent removal of nitrogen, phosphorus, and most heavy metals indicating effective removal mechanisms by the soil during the study period
Contribution to the engineering soil classification of cohesionless soils : final report by Mosaid M Al-Hussaini( Book )

4 editions published in 1977 in English and held by 86 WorldCat member libraries worldwide

This report is a state-of-the-art examination of existing soil classification systems with emphasis on classification of cohesionless soils. The purpose of the report is to note and suggest possible improvements to the Unified Soil Classification System currently used by the Corps of Engineers. Characteristics of soil types pertaining to roads and airfields and soil stabilization' are also considered. Criteria for differentiating between coarse-grained soil groups which have diverse engineering properties, but which are not fully described in other classification systems, are also proposed. Boundaries between clean gravels or sands, gravels or sands with some fines, gravels or sands with fines, and fine-grained soils are suggested as 5, 20, and 50 percent fines, respectively. Coarse-grained soils are also classified with respect to their coefficient of uniformity and coefficient of curvature as well graded and poorly graded, with the poorly graded further separated into narrow (i. e. uniform) and gap gradations. Criteria to separate each group are presented
An evaluation of movable-bed tidal inlet models by Subhash C Jain( Book )

2 editions published in 1979 in English and held by 85 WorldCat member libraries worldwide

The objective of this study was to evaluate the effectiveness of movable-bed tidal inlet hydraulic models in predicting prototype behavior, by comparing model predictions with the observations made in the prototype, and to examine the scaling requirements for such models. Seven model studies were conducted by WES during the period 1939 to 1969. Calibrations of five of these models, as measured by bed topography changes, are evaluated by means of quantitative indicators, including correlation coefficients and root-mean-square (rms) error. The values of correlation coefficients, disregarding measurement errors in model and prototype soundings, were generally low and those of rms error high. Evaluation of data from the Galveston Harbor entrance model revealed that the shoaling rates and distribution along the navigation channel predicted by the model are not in good agreement with the prototype data. It was concluded that the model reproduction of details of bed topography was less accurate than that which might have been obtained had the proposed similitude criteria been used, and had more complete prototype data been available for calibration. Disagreement between model and prototype is believed to have been due to: scale effects introduced by nonsimilarity ofthe physical processes; insufficient prototype data for calibration and verification; oversimplification of the available prototype data for use in the model study; and experimental errors
An investigation of the natural microscale mechanisms that cause volume change in expansive clays by Donald R Snethen( Book )

3 editions published in 1977 in English and held by 85 WorldCat member libraries worldwide

The report concludes a study of the natural microscale mechanisms which cause volume change in expansive soils. The mechanisms were defined and attempts were made to delineate the roles of the mechanisms in the volume change process by inferring the respective influence from observed physical, physicochemical, and mineralogical data. The three major microscale mechanisms which cause the volume change are clay particle attraction, cation hydration, and osmotic repulsion. These three major mechanisms can be represented by the total soil suction which is composed of two components, matrix and osmotic. The matrix component represents the clay particle attraction and cation hydration mechanisms. The osmotic component represents the osmotic repulsionmechanism
Geologic, geoarchaeologic, and historical investigation of the discovery site of ancient remains in Columbia Park, Kennewick, Washington( Book )

1 edition published in 1998 in English and held by 85 WorldCat member libraries worldwide

The site of the discovery of the ancient human remains known as Kennewick Man has gained international attention. On-site study during December 1997 focused principally on one question: is the geologic setting consistent with the 9,OOO-yr age reported for the human remains? Other objectives for the study included determining if there was evidence for a specific cultural affiliation for the remains, if there was evidence for either intentional of accidental burial, and if the stratigraphic layers were in place. The principal landform at the site is a terrace of the Columbia River, comprising fine-grained sediments accumulated in quiet water. The presence of the Mazama teptira, a volcanic ash later correlated throughout the Pacific Northwest, established that this landform is more than 6,700 years old. Stratigraphic horizons traceable over the length of the study site provided datable materials to indicate that the layers are relatively undisturbed and span at least 15,000 years of geologic time. No evidence for cultural affiliation was encountered, and the question of accidental versus intentional burial is still open. The limited scope of this study did not allow definition of the three-dimensional geometry of the landform and its relationship to regional geology

This report documents the history of a program initiated in 1946 to evaluate materials for use as chemical soil stabilizers by the military. A number of Government agencies, universities, and private firms were involved in the program. In addition, many other companies submitted candidate materials for evaluation. Appendix A presents documentation of all materials evaluated including category, components, cost, applicability with regard to soil type, mixing capability, and related effectiveness. Also given are the agencies which conducted the evaluation and appropriate references in which more detailed information of the materials can be found
Model materials evaluation : sand tests ; a hydraulic laboratory investigation by Ernest C McNair( Book )

4 editions published in 1976 in English and held by 82 WorldCat member libraries worldwide

A laboratory investigation was performed to define responses of a natural quartz sand to various hydraulic conditions. The results demonstrate the performance of the material in a movable-bed model and, when compared with the responses of other materials, may provide a basis for the selection of optimum materials for various movable-bed modeling requirements. Twenty-one tests were performed with a 40-ft-long beach containing an inlet and with unidirectional, steady flows through the inlet substituting for tidal flows. The geometric characteristics of the inlet channel, beach profiles, inlet configurations, and material transport were observed for conditions with and without waves and for various magnitudes of flood and ebb flows. The tests showed that the minimum channel area, the channel width at the location of the minimum area, and the hydraulic radius at the location of the minimum area were strongly related to the rate of flow through the channel. The rate of material transport was found to be weakly related to channel flow rate, but the sparseness of data observations with time precluded definite evaluation of this. The ability to scale channel geometry was demonstrated. The rate of material transport appears to be a scalabe quantity, but the scaling relations require additional experimentation for definition.

Physical model simulation of the hydraulics of Masonboro Inlet, North Carolina by Richard A Sager( Book )

2 editions published in 1977 in English and held by 80 WorldCat member libraries worldwide

This report is part of the General Investigation of Tidal Inlets 'Inlet Hydraulics Study.' The study involves the investigation of the tide- and wave-generated flow regime and water-level fluctuations in the vicinity of coastal inlets. Masonboro Inlet was selected as an inlet to be used in determining the usefulness and reliability of physical and mathematical models in predicting hydraulic characteristics of inlet/bay systems. This report presents results obtained from the physical model study. The Masonboro Inlet fixed-bed model, constructed to scales of 1:300 horizontally and 1:60 vertically, reproduced an area extending to the -45 ft contour in the Atlantic Ocean and to the nodal points in each interior channel. The wetlands were accurately reproduced near the inlet; but those areas farther bayward, being relatively flat, were reproduced schematically and artificially bent into the research flume to provide storage for the tidal prism. The model was equipped with appurtenances necessary for accurate reproduction and measurement of tides, tidal currents, waves, and other significant prototype phenomena. Model verification tests assured that the model hydraulic regimen was in satisfactory agreement with that of the prototype. Five velocity ranges with three stations at each range were verified in the model (readings were taken at three depths at each station); and seven tidal elevation gages in the ocean and bay were also verified
Wastewater treatment on soils of low permeability : interim report by Ronald E Hoeppel( Book )

2 editions published in 1974 in English and held by 80 WorldCat member libraries worldwide

The study was limited to land treatment as a means of achieving advanced wastewater purification. Land treatment has the advantage of incorporating the recycling concept directly into its treatment mode, resulting in replacement rather than depletion of natural resources. Also, some form of control over ecologically damaging components is retained. This report presents results of a literature review on various methods of treating wastewater on land and also presents results of model tests of the overland flow method, with particular emphasis on nitrification and denitrification. Two types of soil systems for overland flow treatment of wastewater were investigated during these model tests. One soil was from an 8-year-old commercial cannery wastewater treatment site. The other was from an untreated natural site in a national forest that was low in indigenous soil organic matter; consequently, this latter system was amended with sludge in order to increase its organic matter content. Thus, both experimental soils represented soil systems that had more organic matter and biological activity than an average heavy clay soil
Mechanical constitutive models for engineering materials : final report by Behzad Rohani( Book )

5 editions published in 1977 in English and held by 79 WorldCat member libraries worldwide

Some of the basic mathematical tools and physical concepts necessary for development of mechanical constitutive relationships are reviewed and presented in orthogonal Cartesian coordinate system, using both indicial and matrix notations. Following this review, various classes of isotropic constitutive relationships are discussed and examined. The analyses are restricted to deformation for which displacement gradients are small. The constitutive relationships are classified and presented in the following categories: Constitutive equations of elastic materials, Incremental constitutive equations, Constitutive equations of simple viscoelastic materials, and Constitutive equations of plastic materials
