首先完善上下负荷面中超固结状态参量 R 与结构性状态参量R *的定义表达，并以此重新推导了应力诱导各向异性上下负荷面模型，并在数值程序中再现该模型，实现土的统一本构的数值化模拟。分析了黏土以及砂土的力学特性，及其在数值模型状态变量中的差异，为模拟含黏粒砂土的实现进行理论分析。通过参数试算找出含黏粒砂土的不同黏粒含量分别所对应的模型参数。

The definitions of overconsolidation state parameter R and structural property state pa-rameter R * are perfected,and a new derivation of the super/subloading yield surface model is of-fered based on these definitions.The numerical implementation based on this unified constitutive model is compiled,and the simulation is carried out.The mechanical characteristics of clay and sand and the differences between their state parameters are analyzed.The numerical implementa-tion of clayey sand is then simulated based on the theoretical analysis.To find the correspondence between the numerical parameters and the clay content,simulations of clayey sand with varying parameters are carried out.
