摘要
对小浪底水库区城崖地、塔底、石井河等主要活动断层的基本特征作了简要介绍。采用断层强度分析法分别估算了小浪底水库蓄水前和一些断层面的抗滑稳定系数 ,对库区地震活动性、应力状态、岩溶和岩体渗透性等诱震条件进行了分析。对水库诱发地震的最大震级和可能的震中位置进行了初步预测。
A brief introduction has been done for the basic features of Chengyadi fault , Tadi fault and Shijinghe fault etc.in Xiaolongdi reservoir region.The stabilized coefficients of resistance to sliding of some fault surfaces before and after the filing in Xiaolangdi reservoir are estimated respectively by using the analysis method of fault density. The inducing earthquake conditions such as the seismicity, stress state,karst and permeability of rock in the reservoir are analyzed , and the maximum magnitude and possible epicenters of induced earthquake are forecasted initially.
