In order to find out the underground strata fracture situation within a certain range of domestic waste disposal site in Shuangluan district of Chengde and its surrounding areas, and assist the relevant departments to carry out soil pollution prevention and control projects in the area, the high density electrical method technology was used to detect the area and the surrounding areas within a certain range, and the quality of the data obtained by the detection was qualified. Through the processing and analysis of the detection data, 15 abnormal areas were delineated by the high density electrical method. Among them, C1 - C6, C8, C10 and C12 - C15 were relatively low-resistivity anomalies, and C7, C9 and C11 were relatively high-resistivity anomalies. The detection purposes and tasks were well completed, and good results were achieved.
