针对面板堆石坝在地震荷载作用下坝体应力和永久变形过大以及面板接缝容易损坏的问题，采用等效线性本构模型，利用加速度时程输入的方法，对河口村面板堆石坝进行三维非线性有限元分析，给出了地震过程中大坝的地震加速度、应力、永久变形的分布图以及面板的应力、挠度和接缝变形的大小。分析结果表明，在设计水位加地震荷载工况下，坝体的抗震性较好。

In view of the problems of stress,permanent deformation and slab joints of the concrete face rockfill dam was too big and easy to damage under the earthquake load,this paper based on the equivalent linear constitutive model,used the method of acceleration time history to take three-dimensional nonlinear finite element analysis of Hekoucun Concrete Faced Rockfill Dam and gave the distribution of acceleration,stress,permanent deformation and the stress,deflection and the deformation of joint panel size in the process of earthquake. The analysis result shows that under the design water level and the earthquake load,earthquake resistance of the dam body is safe.
