摘　　要：结合一个具体工程实例,针对复杂地质条件下的公路隧道进/出洞口边坡工程施工,探讨了有效减小雨水渗流,降低滑坡风险的边坡防护和加固处理的方法;在实施过程中对坡面沉降和爆破震动进行了监测,及时反馈信息并对施工工艺进行优化调整,为同类工程提供了可借鉴的经验。In accordance with an engineering project,aimed at the slope construction of highway tunnel at the entry or exit location under complex geological conditions,a slope protecting and strengthening method which can reduce rainwater seepage and decrease the risk of landslide effectively was discussed in the paper.The subsidence of the slope and the blasting shock were monitored in the process of slope excavation,and the information of monitoring was fed back timely to optimize the construction process.The method can provide a useful experience for similar projects.
