摘要： 选择合适的接触面模型对分析土体应力应变关系至关重要。对常用的双曲线模型和修正R-O模型的优缺点进行评述，并从能量耗散角度考察接触面静、动力剪切系统，推导了3参数接触面模型。基于最小二乘法，选用合适的评价标准，证实该模型能够较好地模拟多类土体和多种材料之间的静动力剪切特性，具有较广泛的适用性。

Abstract: The selection of a proper interface model is very important in simulating the stressstrain behavior of soil mass. The paper evaluates the conventional hyperbolic and modified RambergOsgood interface models. From the energy dissipation point of view, the static and kinematic shear system is analyzed and a new threeparameter interface model is derived. The experimental studies also show that this new model can appropriately simulate various interfaces between soil and other materials.
