摘要
结合甬台温铁路太坤山隧道的工程实例,介绍了隧洞穿越浅埋、富水、围岩破碎带的施工技术,阐述了施工中综合运用的截排水、地表注浆、微震爆破及动态监控等措施,指出隧道开挖时应分析各种原因,综合治理,其中治水是关键。
Combining with the project of Taikun mountain tunnel, it introduces the construction technology of tunnel through the shallow, water-rich and rock fracture zone, describes measures in construction, such as cut-off drainage, surface grouting, slight dynamite and dynamic monitoring, and points out that it should analyze all kinds of causes in the process of tunnel excavation, get comprehensive control, and the water control is key.
