摘　　要：基于三维非线性动力有限元分析方法,对平寨水库混凝土面板堆石坝进行地震反应特性研究。针对坝体动力加速度反应、地震残余变形、面板应力及周边缝变形以及坝坡的抗震稳定性对建于峡谷区200 m级高混凝土面板堆石坝进行综合评价,揭示峡谷地形高混凝土面板堆石坝地震反应的一般规律,研究高面板坝的抗震稳定性,并建议相应的抗震设计工程措施。Based on the method of three dimensional non-linear dynamic FEM,this paper analyzed the seismic response behaviors of Pingzhai concrete face rockfill dam.The general rule of seismic response of high concrete face rockfill dam in the level of 200 m which is built in narrow valley was exposed by the analysis of the dynamic acceleration response of dam body,the earthquake-induced permanent deformation,the concrete stress and joint displacement,the aseismic stability of dam slope.This paper had analyzed the seismic stability of high concrete face rockfill dam and had suggested the corresponding engineering measures of seismic design.
