Xiangyang Forest Recreation Area is a large-scale landslide potential area which groundwater of the tourist center was high for a long time. In order to prevent the groundwater from affecting the slope stability, this paper uses the earth electrical logging method to investigate and analyze the stratum characteristics. A total of 5 lines and 29
measuring points are set. The depth of each measuring point can reach 9-33m. The data obtained by the detection is
used to analyze the characteristics of ρa-a curve, plotted as 2D electrical stratum profile, and compared with the dip
tube and drilling data. The results show that the main stratum structure is mainly composed of brown-gray sandstone and slate aggregated fractured layer and fractured slate belt. The structure is characterized by poor fractured slate and quartz as the main distribution area of high aquifer in the area. By comparing with the displacement in the ground, the displacement pattern of the tourist center stratum is almost dominated by stratigraphic compression, and the variation interval mainly occurs in high water-bearing areas. Therefore, it is recommended that the horizontal water collection pipe project should be used to eliminate the groundwater, so as to increase the slope stability.
