The primary focus of the research is in the area of prediction of boundary value problems based on non-linear elasto-plastic finite element analyses. The goal is to develop a deep understanding of the failure mechanisms and possible preventive measures through a research program which involves various facets of geotechnical engineering. The research plan includes: 1. Experimental program to characterize the material: 2. Constitutive modeling (elasto- plastic) including undrained analyses; 3. Optimization based procedures to obtain the model parameters; 4. Finite element analyses with localization analyses.

本文主要研究基于非线性弹塑性有限元分析的边值问题预测问题。其目的是通过一个涉及岩土工程各个方面的研究计划，深入了解破坏机制和可能的预防措施。研究计划包括：1.材料特性的实验程序：2.包括不排水分析的本构模型(弹塑性)；3.基于优化的程序以获得模型参数；4.有限元分析和局部化分析。
