摘要
针对复杂地质条件下公路隧道下台阶施工方法进行了分析,提出了半幅开挖及拉中槽开挖两种开挖方法,并取得了良好的施工效果,为类似隧道施工提供了经验。
The paper analyzes the construction method of lower bench in complicated road conditions,points out the two excavation methods,that is,the half excavation and the cutting middle groove excavation,and achieves better construction effect,so as to provide experience for similar tunnel construction.
