Using the method of soil radon concentration profile measurement, the authors study the Dawugang, Shawan and Chencun faults, which are the concealed faults of middle segment of Baini-Shawan fault zone. The authors can obtain the measurement values of soil radon and delineate soil radon anomaly zones by calculating background value and anomaly threshold of soil radon. Then, the authors analyze the relation between soil radon anomaly zones and location of concealed fault. The results show that the west of No.6 measuring line is the region where Chencun Fault runs through, the west of No.21 measuring line is the region where Shawan Fault runs through, the east of No.22 measuring line is the region where Dawugang fault run through. It is the basis for the further verification on the location, strike and dip of Dawugang fault.
