| Abstract: | In August 2019, when typhoon "liquima" passed through, a landslide occurred in Shuijingbeicun in the southern mountainous area in Ji''nan city. According to geological background of Shuijingbeicun landslide, geophysical exploration, drilling and other exploration methods are arranged to study the engineering geological characteristics of landslide, and analyze the types and geological mechanism of Shuijingbeicun landslide. The rigid limit equilibrium method is used to study the overall stability of Shuijingbeicun landslide. It is concluded that the development of faults, rock weathering, topography and shallow aquifer are seriously affected by rainfall. Rainfall, infiltration of spring water and cultivation are the external conditions of landslide. Under natural conditions, the average stability coefficient of Beicun landslide is 1.033, which is in an unstable state. Under the rainstorm condition, the average value of stability coefficient is 0.903, and the slope is in an unstable state. |
