摘要
在对铜街子水电站蓄水后库坝区及附近出现的地震活动特点进行分析的基础上,对另外一个舟坝水电站库坝区的地质结构和历史地震活动情况进行探讨,认为舟坝水电站蓄水产生诱发地震的可能性较大,五渡—利店断裂附近的马边、沐川、沙湾等地的诱发地震可能为5级以上,犍为县城附近可能出现的地震为4级左右。针对这些问题提出了减轻诱发地震造成损失的相应对策。
We first study the earthquake activities of Tongiiezhi Reservoir region after its storing water and compare the seismological structures and seismicties in historical recordings around Tongjiezhi Reservoir region with Zhouba Reservoir＇ s. Then we present that the similarity in geological condition of both reserveurs may be reasons for similar earthquake tendency, The possible earthquake with Ms5.0 will happen in Mabian, Muchuan and Sawuan areas along Wudu - Lidian fault and the possible earthquake with Ms4.0 will happen in Qianwei area. For this reason we suggest the respond measurements against future earthquakes around Zhouba Reserver.
