城市浅埋水工隧洞暗挖法施工技术

Underground excavation method of shallow hydraulic tunnel in city

结合南水北调西四环暗涵主体工程的概况及其工程特点,从地层加固、土体开挖、初期支护、监控量测等方面对浅埋暗挖法施工技术进行了阐述,以推广该技术在城市水工隧洞施工中的应用。

Combined with major works of covered culverts in south-to-north water transfer project, from reinforcement treatment, soil excava- tion, preliminary bracing, monitoring measurement and other aspects the construction technology of shallow underground excavation method is introduced in order to promote the application of this method in hydraulic tunnel works in city.
