铁路隧道施工关键技术研究

Research on Key Technology of Railway Tunnel Construction

为研究铁路隧道的关键施工技术,依托某铁路隧道工程,总结洞口偏压段的施工技术,分析了沟谷地带浅埋段护拱回填暗挖法的关键施工工序。从研究结果看,使用定型钢模施工明洞段可有效确保施工质量,且拱顶回填施工是护拱回填暗挖法的关键施工工序,在施工时应重点关注。

In order to study the key construction technology of railway tunnel,relying on a railway tunnel project,the construction technology of the biased section of the entrance is summarized,and the key construction process of the backfilling method of the shallow buried section of the buttress is analyzed.It can be seen from the research results that the construction quality can be effectively ensured by using the steel mold to construct the open cavity section,and the arch backfill construction is the key construction process of the backfill excavation method of the arch guard,which should be paid more attention to during construction.
