Geotechnical engineering state of the art and practice : keynote lectures from GeoCongress 2012 by Kyle M Rollins( )

11 editions published between 2011 and 2014 in English and held by 705 WorldCat member libraries worldwide

These keynote lectures were presented at GeoCongress 2012, held in Oakland, California, March 25-29, 2012 and sponsored by the Geo-Institute of ASCE. This book contains 30 peer-reviewed papers that survey the entire breadth of research and practice in geotechnical engineering. Each paper is contributed by distinguished geotechnical engineers who were invited to create a comprehensive overview of the profession by focusing on a specific technical subject. About half the papers present the state of the art by describing current challenges for geotechnical researchers. The other half demonstrates the state of the practice by reporting on issues tackled by geotechnical engineers in the field. Taken together, these papers showcase the best of the profession and form a basis for integrating geotechnical research with its practice. Topics include: foundations and earth stability; geotechnical modeling; site characterization, testing, and monitoring; geoenvironmental engineering; embankments and slope stability; soil properties; pavements; tunneling and underground spaces; and earthquake engineering. This collection is an important touchstone for geotechnical and geoenvironmental engineers, whatever their focus on research and practice. --

Geotechnical Characterization, Field Measurement, and Laboratory Testing of Municipal Solid Waste by American Society of Civil Engineers( )

in English and held by 3 WorldCat member libraries worldwide

Developed from papers and discussions presented at the International Symposium on Waste Mechanics, held in New Orleans, Louisiana, March 11-13, 2008. Sponsored by the Geo-Institute of ASCE. Geotechnical Special Publication No. 209 integrates current knowledge of the properties of municipal solid waste and the challenges it presents with adequate guidance for researchers and practitioners who work directly with issues related to waste behavior. This collection broadens understanding of waste mechanics and improves waste disposal practices both domestically and internationally. The first section is a review of the state of the art in some of the most critical properties of municipal solid waste. The next group of papers attempts to reach some consensus or provide some minimum requirements or recommended procedures for waste characterization. The collection include five opinion papers submitted by the invited panelists from the United Kingdom, Brazil, Canada, Japan, and the United States. This volume will be valuable to researchers and practicing engineers in the field of waste mechanics

Archaeal community structure in leachate and solid waste is correlated to methane generation and volume reduction during biodegradation of municipal solid waste( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Highlights: Concentrations of sCOD, VFAs and DNA in the leachate correlated with CH4 generation. The rate of waste volume reduction correlated with microbial and chemical parameters. Archaeal community structures in leachate and solid waste were similar. Leachate monitoring is useful to evaluate the extent of biodegradation in a landfill. Abstract: Duplicate carefully-characterized municipal solid waste (MSW) specimens were reconstituted with waste constituents obtained from a MSW landfill and biodegraded in large-scale landfill simulators for about a year. Repeatability and relationships between changes in physical, chemical, and microbial characteristics taking place during the biodegradation process were evaluated. Parameters such as rate of change of soluble chemical oxygen demand in the leachate (r sCOD), rate of methane generation (r CH4), rate of specimen volume reduction (r Vt), DNA concentration in the leachate, and archaeal community structures in the leachate and solid waste were monitored during operation. The DNA concentration in the leachate was correlated to r CH4 and r Vt . The r CH4 was related to r sCOD and r Vt when waste biodegradation was intensive. The structures of archaeal communities in the leachate and solid waste of both simulators were very similar and Methanobacteriaceae were the dominant archaeal family throughout the testing period. Monitoring the chemical and microbial characteristics of the leachate was informative of the biodegradation process and volume reduction in the simulators, suggesting that leachate monitoring could be informative of the extent of biodegradation in a full-scale landfill

Strong variation in weathering of layered rock maintains hillslope‐scale strength under high precipitation( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Abstract: The evolution of volcanic landscapes and their landslide potential are both dependent upon the weathering of layered volcanic rock sequences. We characterize critical zone structure using shallow seismic V p and V s profiles and vertical exposures of rock across a basaltic climosequence on Kohala peninsula, Hawai'i, and exploit the dramatic gradient in mean annual precipitation (MAP) across the peninsula as a proxy for weathering intensity. Seismic velocity increases rapidly with depth and the velocity–depth gradient is uniform across three sites with 500–600 mm/yr MAP, where the transition to unaltered bedrock occurs at a depth of 4 to 10 m. In contrast, velocity increases with depth less rapidly at wetter sites, but this gradient remains constant across increasing MAP from 1000 to 3000 mm/yr and the transition to unaltered bedrock is near the maximum depth of investigation (15–25 m). In detail, the profiles of seismic velocity and of weathering at wet sites are nowhere monotonic functions of depth. The uniform average velocity gradient and the greater depths of low velocities may be explained by the averaging of velocities over intercalated highly weathered sites with less weathered layers at sites where MAP > 1000 mm/yr. Hence, the main effect of climate is not the progressive deepening of a near‐surface altered layer, but rather the rapid weathering of high permeability zones within rock subjected to precipitation greater than ~1000 mm/yr. Although weathering suggests mechanical weakening, the nearly horizontal orientation of alternating weathered and unweathered horizons with respect to topography also plays a role in the slope stability of these heterogeneous rock masses. We speculate that where steep, rapidly evolving hillslopes exist, the sub‐horizontal orientation of weak/strong horizons allows such sites to remain nearly as strong as their less weathered counterparts at drier sites, as is exemplified by the 50°–60° slopes maintained in the amphitheater canyons on the northwest flank of the island. Copyright © 2017 John Wiley & Sons, Ltd. Abstract : Seismic velocity profiles across a basalt climosequence in Hawai'i reveal that above a particular precipitation threshold, rapid weathering of high‐permeability layers produces intercalated low‐velocity horizons and dramatically lowers the average seismic velocity of the rock section. However, less permeable layers remain relatively unweathered and thus still contribute significantly to the mechanical competence of the profile, which may explain maintenance of steep‐walled canyons under high precipitation rates. Such observations challenge a top‐down model of progressive weathering (i.e. weakening) of the substrate and therefore suggest that high strength can be maintained even under high precipitation rates, if horizontally layered horizons of different weathering potential exist
