摘要
本文利用四川地区及邻区的烈度衰减关系式,计算了历史强震对大渡河梯级水电站场址的影响烈度和最大烈度。同时,还分析了水电站场址在历史强震发生密集时的地震影响烈度特征,以期为今后梯级水电站的地震安全综合防御和地震应急工作提供参考。
Based on intensity attenuation relationship of Sichuan and adjacent areas, the affected intensity and the maximal intensity on the cascade hydropower stations are evaluated by using historical earthquake catalog. The characteristics of the affected intensity under the clustered earthquakes in history are analyzed, which is expected to provide reference for integrated defense of seismic risk and seismic emergency management of the cascade hydropower stations in Daduhe river in the future.
