摘　　要：文章以重庆石柱至黔江高速公路杉树坪隧道为例,介绍隧道穿越软土层段地基承载力不足、初期支护产生不均匀沉降问题的处治方案,并分析了施工技术要点,明确施工过程中的安全风险措施。通过处治加固,有效消除了隧道施工中的安全风险和后期运营隐患,施工过程安全系数高,施工质量得到保证,隧道顺利穿越软土层段,施工处治效果良好。Taking Shanshuping Tunnel on Shizhu-Qianjiang Expressway in Chongqing as an example,this paper introduces the treatment scheme for insufficient foundation bearing capacity when tunnel passes through soft soil layer section and uneven settlement caused by initial support,analyzes the key points of construction technology,and clarifies the safety risk measures in the construction process.Through the treatment and reinforcement,the safety risks in the tunnel construction and the hidden dangers in the later operation are effectively eliminated,the safety factor in the construction process is high,the construction quality is guaranteed,the tunnel passes through the soft soil section smoothly,and the construction treatment effect is good.
