| 摘 要： | 本文分析了土与混凝土接触面上的剪切变形特性，否定了接触面上剪应力与相对错动位移间的双曲线渐变关系，提出了刚－塑性变形的观点。在此基础上提出了一种有厚度的接触面单元，可以与土体的非线性弹性模型或弹塑性模型相衔接，能合理地反映接触面及其邻近区域剪切破坏带中的变形性状，并提出了确定单元厚度的方法。

| Abstract: | he shear deformation character in the interface between soil and structural material is str-died.The hyperdolic relationship between shear stress and relative shear displacement is denied.The rigid-plastic deformation relationship is suggested.Anew kind of interface element with thickness is de-veloped.It can dovetail with nonlinear elastic or elasto-plastic models of soils,and can reflect the de-formation in the interface and its nearby shear failure area reasonably.Metod of determining the thick-ness of interface element is proposed. |

| Keywords: | interface shear deformation constitutive law direct shear test finite element method |
