摘要
Abstract
Audio magnetotelluric ( AMT) method was employed to study the F2 and F5 branch concealed faults in Suqian sector of Tan⁃Lu fault zone. 4 AMT profiles were finished in the south of Suqian that included 176 AMT sites. By using advanced data processing and 2⁃D inversion called Non Linear Conjugate Gradients, the authors got reliable underground geoelectric models. In combination with the other geophysical data, the authors analyzed electrical structure and explained the location and attitude of F2 and F5 faults, and in⁃ferred that the activity of F5 faults is stronger than that of F2 faults. This result provides the basis of geological line selection and con⁃struction safety for Xusu⁃Huaiyan Railway.关键词
