Abstract: GPR method has been used to detect active faults under shallow overlay. The best parameters of data gathering and optimal processing procedure of the method have been obtained through experiments. The upper conformation and the depth of the top broken points of active faults, as well as the soil structure, can be revealed from the final GRP profiles. With the help of logging information, the activity of active faults can be analyzed and estimated through the GPR profile comprehensive analyzation of the Quaternary structure and the layer position of the top brokenpoints of active faults.

Key words: ground penetrating radar, active fault, top broken-point, fault activity estimation
