摘　　要：推导了三维接触面的弹粘塑性本构关系，并将其与普通单元耦合，研制了三维弹粘塑性有限元软件。以简单案例对有（无）接触面单元物体表面位移进行了对比。The research on the interface consists of two aspects: one is the interface constitution; the other is the interface element. A Goodman interface element is adopted in this study. More attention is paid to the interface constitution. According to the rheologic property of an interface, a elastic-visco-plastic constitutive model is proposed in the paper. It is coupled with the general soil element. A 3D finite element program is developed. Some numerical examples are conducted for checking the constitutive model. It is shown that the calculated displacements of the surface Jump at the interface line and vary with time.
