复杂地质条件城市供水工程输水隧洞施工实践

The construction practice of water conveyance tunnel of urban water supply engineering under complex geological conditions

针对某城市引水工程输水隧洞的区域地质环境和工程地质条件,从钻爆开挖、竖井施工、明洞段施工等方面,阐述了输水隧洞的整体施工方案,提出了隧道施工中破碎松软、渗漏水、流砂、塌方、断层等的处置措施。

According to the regional geological environment and engineering geological conditions of water conveyance tunnel of a city water diversion engineering,from the drilling and blasting excavation,shaft construction,open cut tunnel section construction and other aspects,elaborated the overall construction scheme of water conveyance tunnel,finally put forward the disposal measures of broken soft,permeability water leakage,sand flow,landslide,fault etc. in tunnel construction.
