| Abstract: | 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. |
