摘要:
穿越富水、卵石等地层的地铁隧道地质水文情况复杂，施工难度大，易造成隧道拱顶塌方。这已成为地铁建设中的一大难题。以乌鲁木齐地铁4号线某区间暗挖隧道拱顶塌方事故为案例，提出了事故的综合治理措施。当隧道拱顶出现局部塌方时，可采取加固掌子面、增设拱顶超前小导管及径向锚管加固拱顶围岩等处置方案，达到塌方涌水处置目的。
Abstracts:
Due to the complex geological and hydrologic conditions in water rich pebble layer, the construction of metro tunnel crossing underground the area is very difficult. It is easy to cause tunnel vault collapse, which has become a major problem in metro construction. In the mined tunnel vault collapse of a section on Urumqi metro Line 4, comprehensive treatment measures are proposed. When a local collapse happens at the tunnel vault, the tunnel face should be reinforced, the leading small pipe of the arch and the radial anchor pipe be added to strengthen the wall rock of the arch, so as to stop water gushing from the vault collapse.
