Four types of constitutive models are provided by the code : linear elastic model , duncan - chung model , nonlinear elastic model taking stress path into account and modified three - element model . contact element is used to simulate possible sliding between soil and structure . with this code , analysis is made concerning the pore pressure dissipation , lateral deformation of the support , ground settlement , bottom heave , and variation in earth pressure and support forces ; both effects of consolidation and coupled effects of consolidation and creep are considered ; furthermore , different combinations of cohesion , permeability and excavation width are elaborated
该程序采用了更合理的开挖荷载的计算方法，可以引入线弹性、邓肯张非线弹性、考虑应力路径的非线性弹性和修正三元件模型等四种本构模型，并在挡墙和土之间设置薄层接触面单元以模拟土体和墙体在开挖过程中可能产生的滑移。
