土的剑桥模型发展综述

土的本构理论是理论土力学的重要内容，著名的剑 桥粘土弹塑性本构模型被看做现代土力学的开端，是当前在土力学领域内应用最广的模型之 一。为此简要介绍了剑桥模型及修正的剑桥模型，并对剑桥模型的发展进程作了较为系统的 评述，分析总结了剑桥模型的局限性，指出在剑桥模型基础上针对其局限性进行改进和修正 仍是岩土材料建模的重要方向。

Review of Cam-Clay Model for Soils

Constitutive modeling theory for soils is very significant in geotechnical engineering. The Cam-Clay elasto-plastic model is widely regarded as the milestone of modern soil mechanics. The concept of the model has explicit geometric and physical meanings. The Cam-Clay model and its modified model are regarded as one of several well accepted models among many proposed models. The improvement and revision based on the CamClay model are the important aspect of modeling for geomaterial. In this paper, the Cam-Clay model and its modified model are introduced in brief, its limitation is analysed and an overview on the improvement of this model is given to farther study.
