Non-isothermal dynamic strain localisation in unsaturated porous media

本课题旨在对三维非饱和多孔介质土工结构在热效应、惯性效应和大变形作用下的应变局部化理论进行更全面、更严谨的研究。该项目将增进对处理涉及破坏和不稳定的岩土工程问题的了解和信心。这项研究的结果将是一个经过充分验证的预测工具，其形式为计算模型，用于定量评估结构的完整性、安全性、失效和土工结构(如大坝、堤坝、隧道、斜坡、地上和地下开挖)失效的后果。

This project aims to present a more complete and rigorous treatment of theory of strain localisation in unsaturated porous media geo-structures subject to thermal, inertia and large deformation effects in a three dimensional setting. The project will provide an improved understanding and an added confidence in dealing with geotechnical engineering problems involving failure and instability. The outcome of this research will be a fully validated predictive tool in the form of a computational model for quantitative assessment of structural integrity, safety, failure, and consequence of failure of geo-structures such as dams, embankments, tunnels, slopes, and above and under-ground excavations.
