    Abstract
  • The surface layer of a highway soil-like slope is colluvial soil, underlying strongly weathered-weakly weathered clay shale. It was found that the slope showed signs of deformation and failure in highway operation inspection. The development process, causes and stability of deformation and failure of this soil-like slope were analyzed and studied, the finite element strength reduction method and the circular sliding surface method were used respectively. The results show that the failure mode of the slope is a shallow traction landslide. The calculation results show that the slope is in an unstable state under normal conditions, and abnormal conditions I (rainstorm). Through comprehensive analysis combined with stability calculation, the closed slope surface cracks, prestressed anchor pile with beam, and inclined drainage holes are proposed for treatment. The monitoring data after reinforcement verifies the stability of the slope and the reliability of the regulation plan. The research results can provide a reference for the prevention and control of landslide disasters in soil-like slopes.
