| 摘 要： | 震源机制解表明：长江三峡水库巴东库段地震的发震应力是由库水荷载作用造成的。进一步分析认为，地震可能是库岸区浅地表岩层在库水荷载为主的水岩耦合作用下沿易滑结构面滑动的结果。

| Abstract: | The earthquake location and focal mechanism in the Three Gorges area show that the seismogenic stress of earthquakes occurred in the Badong alongshore, the Three Gorges area is caused by the impoundment of the Three Gorges reservoir. This result also agrees with previous numerical simulation. The gliding of shallow terrane triggered by water loading of the Three Gorges reservoir may be the main mechanism of this earthquakes. |
