| 摘 要： | 在湖南桃源县黄石水库库区，由于张扭性活断层和深部岩溶的存在，水库蓄水后产生的附加应力场及水库区增强的岩石孔隙流体压力诱发了断层的断滑，使得库区应力集中区和岩溶发育区合二为一的地带发生构造型地震，从而在震活动的时间序列、空间规律，地震与库水位关系，震源深度、震情等方面表现出构造水库诱发地震的特点。

| Abstract: | Several reasons including the active tensil-wrench faults, the bond stress due to the filled reservoir and the fault stick-slip induced by high water pressure of small opening triggered the tectonic earthquakes of Huanshi Reservoir region. At the same time the karst caving in happened. The relationship among seismicity the space distribution of earthquake and the water level of reservoir are analyzed. |
