摘要
黄土隧道施工与其它围岩隧道施工明显区别在于黄土隧道施工中围岩收敛大,易产生塌方、渗水、滑塌等地质灾害。本文结合某工程施工经验,探讨了双侧壁导坑法施工准备、初期支护循环衔接、拱脚加固、围岩变形监测等重要技术措施,对同类工程有重要的参考意义。
The most significant difference between loess tunnel＇s construction characteristics and other surrounding rock tunnel＇s is that the surrounding rock convergence is big and easy to produce the geological disasters such as landslides,water seepage,the slump. Based on a certain project in this paper,the important technical measures of both side drift method is discussed,such as construction preparation,primary support cycle,arch foot reinforcement,surrounding rock deformation monitoring. Such an analysis offers reference for the similar projects.
