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，因而其成果更合理些 This paper mainly introduces the results of stress-strain analysis of Shuibuya high concrete face rockfill dam using two-dimensional nonlinear and three-dimensional elasto-plastic finite element method. The research results demonstrate the rationality and feasibility of the design scheme. The elastoplastic model is more reasonable because it reflects the shear-shrinking behavior of the material under high compressive stress
