Construction Technology for High Slope Protection of Deep Excavated Road Cutting in Mountainous Expressway
The high slope of highway cuttings is directly related to the overall quality of the project.If not handled properly,it can cause accidents such as collapse and landslides.This article analyzes the engineering geological conditions and slope stability based on the successful case of the 7-level high slope project of deep excavation of the right side of K66+860-K66+980 section of Foshan-Qingyuan-Conghua Expressway.Starting from two aspects of high slope excavation and protection,this paper deeply analyzes the design of protection schemes and key construction technology points,with a focus on exploring reinforcement and protection construction technologies such as greening protection,anchor rods,anchor cable grids,and monitoring.
