反常系数法在三峡地区断裂活动性评价中的应用

【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更多还原

【Abstract】 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.更多还原
