| 摘 要： | 根据野外考察并结合前人研究成果，对黄河小浪底水库及其邻区地震地质背景进行了分析，对其区域应力状态、断层活动性、地层岩性和地震活动背景等水库诱发地震因素进行了研究。简要地介绍了灰色聚类法，并应用该方法对小浪底水库发生水库诱发地震的可能性及诱发地震震级进行了预测。结果表明，该水库存在水库诱发地震的可能性，其最可能诱发地震的地段及库区中段，水库诱发地震最大震级预测为５级。

| Abstract: | On the basis of field investigation and some others' former results,the seismological and geological background in Xiaoliangdi reservoir area and its vicinity is analyzed.The factors that can induce earthquakes,such as regional stress state,fault activity,stratigraphic lithology etc,are also studied.The grey cluster method is briefly introduced.Using the method,we assessed the possibility and magnitude of potential induced earthquakes in the reservoir.The results show that the possibility to induce earthquakes exists in the reservoir,especially in the middle part of the reservoir area.The maximum magnitude of induced earthquakes predicted is about Ms5. |
