摘要
分析了某黄土隧道塌方的原因,阐述了该隧道塌方综合处治技术和相关的防水、排水措施,采用水泥—水玻璃双液注浆法对其进行加固。监测结果表明:处治后塌方段周边相对位移已处于稳定状态。满足公路隧道施工技术规范要求,说明所采取的综合处治技术措施是有效的方法。
The reason of tunnel collapse is analyzed. The technical parameter of cement-silicate grouting reinforcement and support of surrounding rock as well as its corresponding technology are discussed. The supervising data shows that the surrounding relative displacement of collapse plot of the tunnel after treatment is smaller, which expresses that the whole surrounding rock is stable. The results meet the standard of highway tunnel construction techniques.
