摘要
邓肯-张(Duncan-Chang)模型是描述土体应力~应交关系的一种力学模型,它能够模拟土体发生屈服以后非线性变形的性状,但是忽略了应力路径等因素影响,即假设应力与应变是沿着一条曲线变化的。通过常规三轴试验获得了北京地区亚粘土的邓肯-张模型参数。
Duncan-Chang(E-B)Mode is one of the mechanical models of describing the relationship between stress and strain for soil. It can imitate the non-linear deformation when soil is in yield state, but ignores the influence of stress path,i. e. it is supposed soil stressstrain varying along a curve. In this paper,the parameters of Duncan-Chang(E-B)Model for mild clay are obtained by triaxial experimental study.
