The detection of ground fissures was carried out by using the high density resistivity method and radioactive energy spectrum technology in Longting Town of Hancheng City. To achieve the purpose of detecting fissures, the authors used the difference between the resistivity method and the radiological method to deduce ground fissures of this area, delineate the hazard zones, and select a reasonable relocation range. In this area, the ground fissures resulted from the double influence of the NE-trending large-size concealed structural faults and the slope collapses of the river bank. The detection results show that the integrated geophysical methods have the advantages of effectiveness, convenience and rapidness in the detection of ground fissures.
