Abstract
A high slope in Fuzhou City has a safety hazard problem after slope cutting,and it needs to be reinforced and the effect of the reinforcement program is verified.Based on the stability analysis of the high slope,a representative profile was selected to construct a 3D grid model of the slope,and the plastic zone and displacement of the slope before and after reinforcement were analyzed by the finite difference method under the natural working condition and rainstorm working condition.The maximum displacements were 29.6 mm and 10.8 mm before and after slope stabilization under natural conditions,and 54.9 mm and 27.9 mm before and after slope stabilization under heavy rainfall conditions;the displacements at the six monitoring points on the slope surface were all higher than the displacements before and after stabilization.The displacements of the six monitoring points on the slope surface after reinforcement were greatly reduced compared with the displacements before reinforcement.The numerical simulation results show that the reinforcement scheme of lattice beams plus anchors can effectively inhibit the deformation of the slope and improve the overall stability of the slope.This study has certain reference value for the design and verification of similar high slope reinforcement programs.关键词
