摘要:

以龙厦铁路石桥头隧道Ⅴ级围岩浅埋段为例,在分析、计算地层损失及其诱发的地表变形、埋深对地表变形的影响规律的基础上,对浅埋段地表变形控制等级进行了划分,进而针对地表变形控制等级的不同采用了相应的工法和措施,从而达到了在控制地表变形的基础上提高施工进度的目的。

Abstract:

The tunneling of the shallowcovered section of Shitouqiao tunnel in Grade V surroundingrocks on LongyanXiamen railway is taken as a study case in this paper. On the basis of analysis and calculation of the ground loss, the ground surface deformation caused by the ground loss and the influence rule of the cover depth on the ground surface deformation, the control of the ground surface deformation in shallowcovered section is graded and countermeasures are proposed for different control grades of ground surface deformation. Accordingly, the tunneling speed is guaranteed by the successful control of the ground surface settlement.

Key words: doubletrack railway , tunnel with shallow cover, ground loss, deformation control
