摘　　要："5·12"汶川大地震后,震中地区的水电工程均受到了不同程度的损坏。本文从地震的致灾机理入手,分析了地震的能量释放方式,研究了地震不同能量释放方式与外围地质体的耦合作用所造成的地震灾害的表现形式,并结合映秀湾水电站这一特殊建筑物类型,分析了地震灾害在震中地区水电工程中的主要表现形式及破坏特征,以为地震灾区水电工程的重建工作提供参考,也对高地震烈度区新建和在建工程的枢纽布置、合理规避灾害具有一定的指导意义。During'5·12'Wenchuan earthquake,all the hydropower projects around the epicenter were damaged to different extents.Based on the mechanism of earthquake disaster,this paper analyzes the way of the seismic energy release and analyses the different forms of earthquake damage caused by the coupling effect of both energy release and peripheral geology.Taking Yingxiu Hydropower Station as an example,the paper analyzes and summarizes the main damage forms of hydropower projects in the epicenter of the earthquake.This study provides significant references for the reconstruction of hydropower station in the earthquake disaster area and also the valuable guidance to avoid disasters by reasonably reconstructing new projects in the region of high seismic intensity.
