    REINFORCEMENT METHOD STUDY OF LANDSLIDE BASED ON DIFFERENT DEFORMATION FAILURE MODES

    • There are a lot of landslide geological disasters in our country, and deformation and failure form of landslide is very complex. In order to explore a more reasonable reinforcement method of landslide, deformation process of three types of landslides is analyzed and deformation failure mode of three types of landslides is put forward. Based on the deformation failure mode and engineering geological characteristics of landslide, and correspondingly retrogressive landslide is divided into traction area(initial slide area) and passive traction area, load-caused landslide is divided into pushed area and loading area, combined landslide is divided into leading edge start area(tractive effect),main slide area and trailing edge start area(loading effect).The deformation sequence and interdependence between different areas during the evolution process of landslide are analyzed, and active deformation area and passive deformation area are defined. In addition, the reinforcement method is put forward for different types of landslides based on the deformation and failure mode of landslide. The main idea of reinforcement method is to control the active deformation area and to ensure the stability of the passive deformation area. That different area uses different safety factor to control. And through the calculation and analysis of three typical examples of landslide, this method which has certain application value in engineering practice is demonstrated.
