Theoretical modelling of coupled chemo-hydro-mechanical behaviour of unsaturated expansive clays by
Xiaoqin Lei(
)
2 editions published in 2015 in English and held by 2 WorldCat member libraries worldwide
Expansive clays used in engineering practice are usually unsaturated and are sensitive to chemical composition of the in-pore solution. To analyse the complex coupled problems involved, an efficient mathematical model which can account for these chemo-hydro-mechanical behaviours has been developed. In this thesis, expansive clays are conceptualised into three-phase multi-species porous media. Based on the modified mixture theory and irreversible thermodynamics, a thermo-electro-chemo-hydro-mechanical framework has been developed. The Clausius-Duhem inequality, which governs the dissipations associated with mechanical work, phase transformation, mass transport and thermal transport, is rigorously derived. Based on this thermodynamic framework, constitutive laws for bulk liquid and salt mass transport, free and adsorbed water inter-phase mass transfer, and the chemo-elastic-plastic deformations of soil skeleton have been developed. The model has been implemented into the FEM software Bil and validated by simulating available experimental data on Boom Clays. What's more, the salt infiltration process into an unsaturated expansive clay layer has been simulated to illustrate the applicability of the model

A chemo-elastic-plastic model for unsaturated expansive clays(
)
1 edition published in 2016 in English and held by 1 WorldCat member library worldwide
Abstract: Clays are widely used as sealing materials in various geotechnical and geo-environmental engineering applications. These clays are usually unsaturated and are sensitive to chemical composition of the saturating solutions. During their service period, various mechanical, chemical, and hydraulic loading conditions, usually coupled with each other, can be encountered. It is necessary to use a chemo-elastic-plastic unsaturated model to account for these coupled loading paths and simulate the possible behaviours of these clays in their realistic engineering context. In this paper, based on the thermodynamic framework (Lei etal., 2014) for unsaturated expansive clays, the chemo-elastic-plastic model developed by Loret etal. (2002) for saturated homoionic expansive clays is extended to the general unsaturated case. From a theoretical analysis, it is shown that this model is sufficient to simulate the typical behaviours under various mechanical, chemical, and hydraulic loading conditions. The model is then validated against available experimental data of oedometer tests concerning purely mechanical and mixed chemo-mechanical loadings under controlled matric suction on reconstituted Boom Clay mixed with NaNO3 solution. Reasonably accurate estimates of quantitative responses of these complex coupled geochemical loading paths can be obtained, thus giving us a preliminary insight on chemo-hydro-mechanical coupled behaviours
