Abstract:

水库诱发地震是影响水库安全和大坝稳定性的重要因素之一,对拟建大中型水库开展水库诱发地震专题研究是抗震设计的基础性工作之一。中波水电站位于青藏高原东南部的高山峡谷区,地层岩性以浅变质岩和沉积岩为主,玉曲河断裂基本沿库区左岸展布,为晚更新世活动断裂,并与闹中断裂交汇于库区中部。库区地震活动性在频度和强度上相对较低,但震级可达6级。库区有未来发生中强地震的构造背景和条件。在对库区地质环境条件进行调查研究的基础上,采用定性分析法和概率预测法分析,认为中波水电站存在水库诱发地震的可能性。采用水库综合要素法、逻辑信息法和灰色聚类法等方法综合研究表明,中波水电站水库诱发地震震级上限为4.5级,震中基本烈度上限为Ⅶ度弱,最有可能发生水库诱发地震的地段为中波―巴格库段。
