摘　　要：通过横渡水库所在区域地震构造背景、水库影响区及库区断裂活动性等方面的研究,采用构造类比法对横渡水库诱发地震的可能性进行讨论和分析,最终给出横渡水库诱发地震的可能性以及一旦诱发地震的最大震级,为水库建成后,可能出现的水库诱发地震问题提供科学依据。Based on the research on the seismic tectonic background,reservoir affected area and fault activity in the Hengdu Reservoir area,the possibility of earthquake induced by Hengdu Reservoir is discussed and analyzed by the structural analogy method and the probabilistic prediction method.Finally,the possibility of the earthquake induced by Hengdu Reservoir and the maximum magnitude of the earthquake once it is induced are given,which provides a scientific basis for the possible occurrence of the earthquake induced by the reservoir after the completion of the reservoir.
