摘要

This paper systematically analyzes the measurement results of soil radon of the Haihe River, Tianjin South, Tianjin North and Cangdong faults, and the activity strength or weakness of the four faults are analyzed and divided in terms of the H value, the association of the M and An value. Through the contrast with the segmentation results of the four faults obtained in the fault exploration, it is found that the two are consistent with each other. At the same time, each method is found to have its limitation. Therefore with the proper selection, soil radon measurements can be a preliminary analysis of fault activity and can serve as a reference for the segmentation of fault activity.
