摘要
According to the test results obtained from Olympic Park, Beijing, Shandong Province, Gansu Province and Shanxi Province, the authors have generalized the method and process for inferring the discontinuity of electrical structure (DES) reflecting a buried fault in urban areas from resistivity tomograms and its typical electrical features. In general, the layered feature of electrical structure is analyzed first of all for defining preliminarily whether a DES exists in the target area or not. Then the contours of resistivity in resistivity tomogram are analyzed from the deep to the shallow part. At last, horizontal tracking needs to be carried out for defining the trend of the DES reflecting a buried fault.
