摘要
利用反常系数法对三峡地区的断裂活动性进行了初步研究.结论认为,反常系数在空间上明显呈带状异常分布,断裂通过处K值系数发生突变,在排除非构造因素之后,可作为断裂活动性的一种标志.并进一步认为,三峡地区的高桥断裂、水田坝断裂、雾渡河断裂、仙女山断裂和九湾溪断裂均属活动性断裂
The abnormal coefficient method is used in studying the activity of faults in the Three Gorges region. The results indicates that the distribution of abnormal coefficient has a distinct belted nature. The anomalous value suddenly changes near the faults. This is a sign of active fault. Thus, Gaoqiao fault, Shuitianba fault, Wudu Creek fault, Xiannu Mountain fault and Jiuwan Creek fault are regarded as active faults in Three Gorges region.
