摘要
本文利用有限元方法计算了武隆江口水库蓄水后可能引起的水库诱发地震。在水库底部有断裂通过时,对江口水库在不同的假设宽度情况下进行了分析,给出了水库底部各处的最大剪应力。结果表明,水库底部岩石发生破坏的可能性很大,极可能引起水库的诱发地震,其最大震级为5级左右。
An earthquake in Wulong possibly induced by Jiangkou reservoir impounding is analyzed by using finite element method. When the Jiangkou reservoir is analyzed, its different breadth cases and a zone of fracture going through its bottom are considered, and the maximal shear stress in the reservoir bottom rock is shown. The analysis results are as follows： it is very possible that the reservoir bottom rock will be destroyed, the reservoir-induced earthquake is likely to be induced, and the greatest earthquake magnitude is about 5.
