RIA: Thermal-Mechanical Analysis of Cohesive Soils: A RobustMethodology

本研究的主要目标是发展一种通用但实用的方法来分析各向同性，饱和粘性土，不仅考虑材料非线性和热-力学耦合，而且考虑土壤的时间相关特性；开发一个有效的数值实现所提出的分析方法；并将数值模拟结果与实验室和现场调查结果进行了比较，验证了该方法的有效性。一个广义的弹塑性-粘塑性边界面公式将被扩展以实现这些目标，以推进当前的状态在热和流体通过变形多孔介质的流动模拟。

The primary objectives of this study are to develop a general but practical method for the analysis of isotropic, saturated cohesive soils which take into account not only material nonlinearities and thermo-mechanical coupling, but also time-dependent characteristics of soil; to develop an efficient numerical implementation of the proposed analysis method; and to verify this method by comparing numerical simulations to results of laboratory and field investigations. A generalized elastoplastic-viscoplastic bounding surface formulation will be extended to realize these objectives to advance the current state of the art in the simulation of heat and fluid flow through a deforming porous medium.
