摘　　要：主要介绍采用二维非线性和三维弹塑性有限元法对水布垭高砼面板堆石坝进行应力变形分析研究的成果。研究成果论证了设计方案的合理性和可行性。弹塑性模型由于能反映材料在高压应力条件下的剪缩特性。This paper introduces the results of stress strain analysis on the high concrete faced rockfill dam for the Shuibuya Project by means of 2 D no linear and 3 D elasto plastic FEM, respectively.The results prove that the design scheme is feasible.As the elasto plastic model can reflect the shear contraction characteristics of material at high stress condition,so the result is relatively more reasonable.
