长距离TBM隧洞混凝土运输通道分区规划布置

Zoning Planning and Layout of Concrete Transportation Channels in Long-distance TBM Tunnel

针对长距离TBM隧洞衬砌分布不均且不连续、全断面衬砌和非衬砌段交错布置、全断面衬砌断面类型衬砌厚度不一的特点,对全线TBM隧洞衬砌进行衬砌分区;同时合理规划布置运输通道,便于施工资源人、材、机的投入,大大加快了TBM衬砌施工进度。

Long distance TBM tunnels have the characteristics of uneven and discontinuous lining distribution,staggered arrangement of full section lining and unlined sections,and varying lining thickness of full section lining section types.This paper conducts lining zoning for the TBM tunnel lining along the entire line,while reasonably planning and arranging transportation channels.It facilitates the investment of construction resources,personnel,materials,and machinery,greatly accelerating the progress of TBM lining construction.
