摘要
结合工程实例,从排水、超前预注浆、大管棚超前支护、双侧壁超前导洞开挖等方面,阐述了隧道花岗岩段富水断层的施工方法,并介绍了施工中的监测与应急措施,旨在确保隧道施工的安全性。
Combining with the engineering cases, the paper illustrates the construction methods for the rich water fault of granite section of tunnels from the drainage, advanced pre-grouting, advanced support of large pipe sheds, and two-wall advanced pilot cave excavation, and introduces the monitoring and emergency measures in the construction so as to ensure the safty of the tunnel construction.
