    Abstract
  • Taking the bedding rock slope of Qixia Ancient Town in Nanjing as an example, the stability of the slope after excavation was studied by using the limit equilibrium method and the strength reduction method, and the causes of slope instability and deformation characteristics were analyzed. The reinforcement scheme was designed for the potential landslide problem of the slope, and the reinforcement effect of the bolt under different combinations of length and inclination angle was simulated. According to the slope stability coefficient and the displacement and stress distribution of the slope after anchoring, the bolt length of 7 m and inclination angle of 20° are determined as the best schemes. Combined with other reinforcement measures, the stability of the slope is improved. The analysis results show that the slope stability coefficient after reinforcement meets the specification requirements, and the slope displacement is controlled within the safe range. The reinforcement design scheme is reasonable and feasible.
