摘　　要：基于邓肯E～B模型，对公伯峡面板堆石坝施工期和蓄水期的应力变形进行了非线性有限元仿真计算，研究了其应力变形的变化及分布规律；对主堆石体主要材料参数进行了敏感性分析，探讨了其对高面板堆石坝应力变形的影响特点。<Abstrcat> The stress deformation rules of Gongbo Xia CFRD was analysesed with the nonlinear finite element method based on E～B model. The sensitivity analysis was conducted for principal parameters of major rock fill body, the influence of them on the stress deformation of high CFRD was discussed in the paper.
