Abstract: Based on field investigations we have analysed the conditions of induced earthquakes by the reservoir of the Jiangya Hydropower project. We also made comparison between this engineerning and other reservoirs. Preliminary assessment on possibility of reservoir inducing earthquakes by the Jiangya hydropower project is proposed. It is suggested that the possibility of induced earthqukes exists at the gorge segment where karst developed well. Th possible seismogenic position,maximum magnitude and intensity are also estimated.

Key words: Reservoir earthquake, Induced earthquake condition, Hunan

摘要： 根据野外实地工作,进行水库诱发地震诱震条件的综合分析,并与其它发震水库进行对比,对江垭水电工程水库诱发地震可能性作出初步评价。认为江垭水库蓄水后,在岩溶发育的峡谷地段存在诱发地震的可能性,并对发震地段,最高震级和烈度进行了估计。
