Abstract: Boyang town from Tongdao County is located in the prone area of geological disasters in Tongdao County. It is also one of the towns with the largest number of potential geological hazards and the largest number of threats. On the basis of analyzing the development characteristics of geological disasters in this area, taking Loutuan Landslide as the research object, this paper analyzes the spatial form, material composition and deformation characteristics of the landslide, adopts the limit equilibrium method, selects the broken line sliding model, calculates its stability under two different working conditions, and finally evaluates the stability of the landslide. It is concluded that under condition 1, it is basically stable, and under condition 2, it is under stable unstable. It is proposed that the measures for the treatment of Loutuan landslide include anti slide pile engineering, surface water interception and drainage engineering and slope ecological engineering. The research results will provide basis and reference for the treatment of this landslide.
