1) double down-side drifts
双下侧导坑
1.
Confronted with accidents in a shallow-buried weak tunnel through old road using the bench excavation method,such as great subsidence and cracks in the ground surface as well as those in the preliminary support,a double down-side drifts construction method was presented.
针对某隧道软弱围岩下穿公路段在原台阶法施工中出现地表下沉、开裂等问题,提出双下侧导坑施工方法,分析其传力机制,并应用MIDAS软件建立仿真模型,进一步研究该工法的施工性态。
2) double side-wall heading excavation
双侧壁导坑
1.
According to the complex geological conditions of the upward tunnel in the shallow buried area,a more secure method of double side-wall heading excavation method is used.
根据仰口隧道浅埋区的复杂地质条件,采用了较为安全的双侧壁导坑法开挖,这种施工方法有其自身的诸多优点,在开挖时,它的断面是分为多个工作面施作,每一个开挖工作面在初支作用下立即形成应力闭合状态,充分利用围岩的自承能力,很好控制了整个施工过程中的应力变形量,为施工创造了良好的经济和社会效益。
3) double side drift method
双侧壁导坑法
1.

结合京珠国道主干线广州东段龙头山隧道施工,重点介绍隧道开挖采用的双侧壁导坑法、超前支护以及初期支护,可供类似工程施工参考。
4) both side heading method
双侧壁导坑法
1.
Application of the both side heading method in the large span tunnel construction
双侧壁导坑法在大跨度隧道施工中的应用
2.
