摘　　要：以往的土体材料本构模型基本上没有考虑结构性这一最为根本的内在因素的影响 .在回顾与评价剑桥模型的基础上 ,基于经典塑性理论 ,提出了一个可考虑结构性影响的土体本构模型 ,分析验证了这一模型的合理性 。In previous geomaterial constitutive models, the influence of soil structure which is the essential intrinsic factor has not been taken into account. Based on the Cambridge model and classical plastic theory, a constitutive model which considers the influence of soil structure is proposed in this paper. Its rationality was analyzed and verified, and its applicable scope is pointed out.
