摘要
介绍了一公路隧道工程设计概况,阐述了Ⅱ、Ⅲ类围岩段双侧壁导坑施工方法及Ⅳ、Ⅴ类围岩段台阶施工方法,并对偏压段施工方案中围岩的稳定性进行了优化数值分析,获得了偏压大跨隧道双侧壁导坑法的合理施工工序。
In this article, authors introduce the general situations of a mad tunnel project. The construction technology of two-side wall drift heading in Ⅱ , Ⅲ rock and benching tunneling method in Ⅳ, Ⅴ rock are presented. And a reasonable construction procedure is got by optimization analysis of rock stability under biased press.
