摘要
以簸箕岭隧道施工为背景,着重阐述了采用浅埋地表注浆加固处理、超前管棚支护、单侧壁导坑开挖等施工技术进行小净距浅埋偏压隧道施工,实践表明,这些方法对控制浅埋偏压隧道洞口地表及拱顶下沉、山体偏压对隧道造成的偏移等效果十分显著,对类似隧道施工具有一定的借鉴意义。
Based on the construction of Bojiling Tunnel, the methods adopted in the construction of neighborhood unsymmetrical pressure tunnel are explained, including shallow buried grout - injection for strengthening surrounding soil, advancing pipe-shed jumbo supporting, one-side-drift excavation and other techniques. Practice has proved these methods can be effective in controlling the subsidence of surface ground and tunnel crown, and displacement due to unsymmetrical hill pressure and can be instructive reference for other similar tunnel construction.
