| 摘 要： | 通过实地考察并结合前人研究成果，对黄河小浪底水库及其邻区地质构造特征和地震活动性进行了分析，认为该地区地质构造背景较为复杂，地震活动性相对较弱，在此基础上，采用概率预测法对小浪底水库诱发地震的可能性进行了研究，利用逻辑信息法和灰色聚类法对诱发地震的强度进行了预测，结果表明，该水库存在诱发地震的可能性，最可能发生诱发地震的地段为库区中段，震级上限可达5级。

| Abstract: | On the basis of field investigation and former studies,the geological structures and seismicity in Xiaolangdi reservoir and its adjacent area are analysed.It is considered that the geotectonic background is complex and seismicity is relatively week in the area.By using probabilistic statistic method,logic information method and gray cluster method, possibility and magnitude of induced earthquake of the Xiaolangdi reservoir are forecasted.The result shows that there is the possibility of the induced events,especially in the middle segment of the reservoir and the maximum magnitude could be 5.0. |
