摘　　要：在浅覆盖区采用探地雷达探测地震活动断层。通过实验确定出最佳的采集参数和数据处理流程,在雷达剖面上,能够清晰地显示出断层上部的形态特征、上断点埋深和岩土分层。结合钻孔资料,利用雷达剖面上对第四系覆盖的分层结果和上断点所在的层位可以分析和评价断层的活动性。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.
