摘要
明挖法和盖挖法在隧道过河段施工中均有各自优势。以兴泉铁路某隧道过河段施工为例,通过两种施工方法的比较,分析了明挖存在的问题和容易产生的不利后果,优选采用拱盖盖挖法施工,并围绕拱盖设计、施工步骤、施工注意事项、取得效果等阐述了拱盖盖挖法施工。结果表明,通过过程控制,拱盖盖挖法施工在工期、安全、成本、质量等方面取得积极的效果,凸显了该方法的施工优势,为类似工程施工提供了借鉴。
Open excavation method and cover excavation method both have their own advantages in tunnel crossing construction.Through the comparison of two construction methods in the construction of a tunnel crossing the river in XingquanRailway,the problems existing and the adverse consequences in open excavation method is analyzed and cover excavation methodis adopted,focusing on arch cover design,construction steps,construction regulations and the effects.Through the process control,the arch cover method achieved positive results in terms of time limit,safety,cost and quality with its constructing advantages,providing reference for similar engineering construction.
