摘要
某地在滨海相淤泥质地层中用浅埋暗挖法成功施作了地下过街道,打破了淤泥质地层是暗挖禁区的观点。从这一案例出发,简要地论述了注浆对地层的改良效果以及浅埋暗挖施工工艺在淤泥质地层中的应用方式,为在其他淤泥质地层中进行暗挖施工提供了实践经验。
The shallow excavation technique was successfully implemented in constructing the underground passage in a slit formation, which breaks the point that slit formation is the forbidden region for excavation. Starting from this case, this paper elaborates on the improving effects of grouting on the formation, and the application methods of shallow excavation technique in the slit formation, which can be reference to similar projects.
