摘　　要：选用等效线性本构模型模拟了土石坝材料动力特性,采用有厚度薄层接触单元模拟了混凝土坝与土石坝软接头接触面,并通过时程分析方法对规则侧墙式混合坝算例进行有限元动力计算,分析了接头处接触面动力反应对于接触面坡度变化的敏感性。In this paper, the equivalent linear elastic constitutive model is chosen to analyze the dynamic response characteristics of material for soil and debris filled dam,and thin-layer contact elements are used to simulate soft joint surfaces between concreted dam and mixed dam. It takes the regular wall-sided mixed dam as an example to establish FEM model and calculate dynamic force by time-process analysis method. Sensitivity to dynamic response with slope of the contact surface is also analyzed.
