| 摘 要： | 根据摩尔－库仑破裂准则，利用库区应力摩尔圆的移动和半径的变化以及岩石破裂线的变动，分析了库区不同区域的诱震机制，指出水库诱发地震易发生在断裂带及其附近，断层穿过库心正下方时大大增加诱震的危险性；分级蓄水则可以减小诱发快速响应型地震的可能性。

| Abstract: | Based on Mohr-Coulumb rupture principle, the mechanisms of induced earthquake in different parts of reservoir zone are analyzed, in which both the changing of the Mohr circle and the changing of the rupture line are considered. Some other conclusions are as follows: it is easy to induce earthquake inside and near fault; the existing of the fault passing through right under the reservoir center increases the possibility of induced earthquake greatly; and slow impending decreases the possibility of earthquake with rapid response type. |
