某公路隧道穿越断层破碎带施工技术

Construction Technology of a Highway Tunnel Crossing Fault Fracture Zone

文章以某公路隧道建设工程为例,分析断层破碎带对道路隧道施工造成的影响,介绍隧道穿越断层破碎带施工过程中的技术要求。基于施工方案、支护体系、土石方开挖等多个层面对问题展开调研,总结实际施工过程中可能面临的问题,意在提高道路隧道建设水平,推动我国交通事业进一步发展。

Taking a highway tunnel construction project as an example, this paper analyzes the influence of fault fracture zone on road tunnel construction, and introduces the technical requirements in the construction process of tunnel crossing fault fracture zone. Based on the construction scheme,support system, earthwork excavation and other aspects, the problems is investigated in this paper and the problems may be faced in the actual construction process are summarized in order to improve the level of road tunnel construction and promote the further development of transportation industry in China.
