| 摘 要： | 大管棚超前注浆预支护(以下简称大管棚)作为地下工程与隧道工程暗挖法施工的一种超前支护手段,在公路和铁路建设中逐渐得到广泛的应用。如隧道内地质条件差,围岩松散,自稳能力差;隧道穿越地表高层建筑物,既有公路或铁路时埋深浅,而此时又因为种种原因不能采用明挖法施工;大跨度隧道(如车站隧道及三车道以上隧道)和小净距隧道的施工;隧道施工中出现的坍塌等等情况时可考虑采用大管棚施工。

| Abstract: | As a pre-support technique of tunneling construction technology in underground construction and tunnel, leading steel pipeline shed previous timbering technology has became gradually popular. If there exists weak ground soil, loose soil, weak self-stabilization in tunnel, or tunnels through ground surface high-rise buildings, shallow burial depth when railways and roads are concurrence, on this condition it is impossible to apply the open excavation technology, wide-span tunnel (railway station tunnel and three-lane (or more) road tunnel), and small-distance tunnel. Also, steel pipeline shed construction technology can be applied in case of collapse during tunnel construction. |
