特长隧道洞内平面施工控制测量技术探讨

Discussion on Horizontal Control Survey for Construction of Extra-long Tunnel

以秦岭隧道工程为例 ,以测量设计为前提 ,全面论述了特长隧道洞内平面控制测量的技术要点、施测过程中的具体要求及注意事项 ,同时 ,对适应TBM施工测量技术的IED - 2 6

Taking Qinling Tunnel as an example and on the premise of survey design,the technical points, concrete requirements and items for attention of horixontal control survey in extra-long tunnel are expounded in this paper Meanwhile,operating principle as well as the usage of IED-260 tunnel guiding system which adapting to TBM construction survey technique are also briefly introduced.
