X输水隧洞施工TBM选型

TBM Selection for X Water Conveyance Tunnel Construction

甘肃省X输水隧洞穿越军事禁区,导致无法布设施工支洞,也不宜采用传统的钻爆法施工。为保证建设工期,隧洞采用了TBM施工方案。文章从输水隧洞围岩条件、施工进度及工程造价等方面,进行TBM施工系统选型,对长距离输水隧洞施工的TBM选型提供决策参考。

X water conveyance tunnel in Gansu Province passes through the military forbidden zone,which makes it impossible to deploy construction adit,and it is not suitable to adopt traditional drilling and blasting methods.In order to ensure the construction period,the TBM construction plan is adopted.The article selects TBM model from the aspects of surrounding rock conditions,construction schedule and project cost of the water conveyance tunnel,and provides decision-making reference for the TBM selection of long-distance water conveyance tunnel construction.
