    Abstract
  • The Fengshushan landslide is a traction landslide caused by a cutting slope of engineering construction. Through geological survey, drilling, well exploration, soil test, and comprehensive analysis, the development process of landslide, the basic characteristics of landslide, and the geotechnical characteristics of fault zone were found out, and the stability and deformation trend of landslide were systematically analyzed. Comprehensive treatment measures such as cutting slope and reducing load, setting up the anti-slide pile and anchor cable (anchor rod) frame beam combined support structure, drainage system improvement, and slope greening were put forward. The results show that the geological conditions in the study area are complex, faults are developed and groundwater is abundant in the tectonic belt. The mechanical properties of the silty clay formed from the weathering of the fault structural rock are weak, which are the important conditions for the formation of landslides. Excavation of slope feet and continuous heavy rainfall are the main inducement of landslides. The research results provide a reference for urban geological surveys and similar landslide engineering prevention.
