摘要
隧道进出洞口边坡稳定是影响隧道安全施工与正常运营的主要因素之一。分析了粤境某隧道进口山体的工程地质条件,基于GEO-Slope软件对隧道进口山体的稳定性进行了分析计算,确定了边坡的潜在滑动面,简要分析其潜在变形因素,并在此基础上提出了后续处治对策,希冀为类似工程提供借鉴。
Slope stability at the entrance and exit of tunnel is one of the main factors affecting the safe construction and normal operation of tunnel.In this paper,the engineering geological conditions of a tunnel entrance mountain body in Guangdong Province have been studied.Being based on GEO-Slope software,the stability of the tunnel entrance mountain body has been analyzed and calculated,the potential sliding surface of the slope has been determined,the potential deformation factors have been briefly analyzed,and on this basis,the following treatment countermeasures have been put forward,which could provide references for similar projects in the future.
