摘要： 采用平面应变有限元方法，对该坝在施工、蓄水过程中的应力变形进行了模拟分析，模拟计算中，砼材料用线 弹性模型模拟，坝体土石料用邓肯．张E-v非线性弹性模型模拟，砼与黏土间的不协调位移用Goodman接触面单元模 拟．坝体的施工过程和蓄水过程均用分级加荷的方法模拟．计算结果表明，坝体应力变形无异常分布，目前的设计是 合理可行的．

Abstract: Stress and deformation of a high rock-fill dam with a vertical soil core on the upper strean of Dadu River during building and filling Was analyzed with plain strain finite element method(FEM)．In computing，linear elastic model Was used to simulate the stress-strain relationship of concrete，and a nonlinear elaStic model，suggested by Duncan and Zhang， Was used to simulate the behavior of dam materimals．An imerface medel sugested by Goodman Was used to simulate the discontinuity deform ation between concrete and clay．The courses of building dam and filling were simulated by increaSing elements step by step．Computing results indicate that the present design of the dam is reasonable because there is no abnormal stresses and deform ations jn the dam ．

Key words: rock-fil dam , finite element method(FEM), stress, deformation
