基于强度折减法的隧道洞口土质高仰坡开挖稳定性分析
Stability analysis of excavation of tunnel opening soil high heading slope based on strength reduction method
摘要
Abstract
This paper deploys three-dimensional stability analysis of one highway tunnel opening heading slope with strength reduction method and calculates the influence of different slope ratios to the stability analysis.It also makes full use of the advantage of strength reduction method and calculates the safety factor of heading slope under the conditions of tunnel excavation and slope reinforcement.This method can provide reference for similar projects.关键词
