Schematization of constitutive models for geomaterials and coherent prediction of the deformation and failure on ground behaviors

本文在总结以往岩土材料本构模型研究及其在岩土工程中的应用的基础上，提出了一种简单而复杂的模型，该模型能独特地描述一般应力系统下的各种土体特征。该模型也适用于各种岩土工程问题的分析。虽然变形和破坏的实际预测是分开进行的，但目前的研究能够从地面变形到破坏进行合理和连贯的预测。

On the basis of the past researches on constitutive modeling of geomaterials and its application to geo-engineering problems which have been done in our laboratory, a simple and sophisticated model which can describe uniquely various soil features in general stress systems is presented. Also, this model is applied to the analyses of various geotechnical problems. The present research enables the ration and coherent predictions from ground deformation to the failure, though practical predictions of the deformation and failure have been done separately.
