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.

该项目旨在提出一个更完整和严格的处理理论的应变局部化在非饱和多孔介质地质结构的热，惯性和大变形效应在三维设置。该项目将提供一个更好的理解和处理涉及故障和不稳定的岩土工程问题的信心。这项研究的结果将是一个充分验证的预测工具，在一个计算模型的形式，定量评估结构的完整性，安全性，故障，以及地质结构，如大坝，堤坝，隧道，边坡，地上和地下开挖的故障后果。
