摘　　要：以某已建工程为例,基于邓肯E-B材料本构模型,对混凝土面板堆石坝次堆石区采用软岩料填筑和硬岩料填筑两个方案进行三维有限元分析,分别获得软岩料填筑和硬岩料填筑时坝体应力变形的分布与变化规律。通过有限元计算分析,可以看出采用软岩填筑面板坝是可行的。Taking one built project for example,based on the Dengken E-B constitutive material model,the 3-D nonlinear finite element analysis for the stress-deformation of the dam whose ⅢC filled soft rock material and hard rock material was carried out,and the stress-strain distribution and variety rule for the dam were obtained.It is believed that the CFRD constructed with soft rock is feasible by finite element analysis and calculation.
