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 ,指出了模型的适用条件 In the past, constitutive model of soil material basically did not consider the most fundamental intrinsic factor of structure.On the basis of reviewing and evaluating the Cambridge model, based on the classical plasticity theory, a soil structure that can consider the structural influence The constitutive model analyzes and validates the rationality of this model and points out the applicable conditions of the model
