Based on the landslide management in Zhanshi Gully, Well-fragmented County, the stability of the landslide in Zhanshi Gully, Well-fragmented County, was calculated and analyzed by using finite element analysis numerical simulation software, and three support schemes were proposed: anchor support, anti-slip pile support, and the mixed support of anchors and anti-slip piles. After a comprehensive consideration and comparison of the horizontal displacement, effective shaping zone and safety factor of the various support strategies, the composite support method of anchor rods and anti-slip piles is adopted to meet the standard needs of practical engineering applications.
