三峡工程库首区高桥断裂特征与地震活动性研究
|
摘要
用地质学与地震学的研究方法,对高桥断裂的特征及其地震活动性进行了综合研究,研究结果表明:1)该断裂规模较大,为上地壳断裂,断层物质测年表明断裂在晚更新世早期仍有活动;2)断层渗透结构为散状导水结构,有利于库水下渗;3)在三峡水库蓄水前后,沿高桥断裂一带有明显的地震活动;4)三峡水库蓄水后,地震活动主要是以中频度、低强度的形式释放能量;5)在库水作用下,高桥断裂有诱发Ms3.0~4.0地震的可能。
The property and seismicity of Gaoqiao fault is analyzed by use of geologic and seismological method.The results show:1)The scale of Gaoqiao fault is large.It is a fault at the top of the earth's crust.The new aitivity age was earlier period of the late Pleistocenc;2)The perineability structure of the fault is distributed conduit that is useful for infiltration of underground water.3)there are obvious seismic activity before and after impoundment of the Three Gorges Reservoir along Gaoqiao fault zone;4)After impoundment,the seismicity of Gaoqiao fault behaves as a energy releasing in the form of medium frequency and low intensity;5)Gaoqiao fault is a potential seismic risk region in this area and vicinity,where will occur tectonic reservoir-induced seismicity of %M %s3.0-4.0.
