摘要
贵广铁路贺街隧道进口位于浅埋偏压地段,前期施工过程中各种地质灾害屡有发生,并且多次发生大型滑塌、初支侵限、结构大变形现象,对施工进度、安全、质量均产生不同程度影响,为山岭隧道浅埋偏压施工困难之典型。本文系统介绍了如何采取措施确保结构稳定性和综合治理措施以及受力转换合理性,实践证明隧道安全施工得以保证。
The entrance to Hejie Tunnel on Guizhou-Guangdong Railway is located in shallow buried bias section. During the early stage of the construction process, various geological disasters occurred frequently, including many large slump, initial penetration, structural deformation, which greatly affected the construction schedule, safety and quality. Taking the typical model for the mountains and shallow bias tunnel construction as an example, the author introduced measures to ensure the structure stability and comprehensive control measures and stress transformation rationality to ensure the construction safety.
