我国铁路运营里程较以往有了较大的发展,但路网布局不均衡,主要集中在中东部地区,今后的建设重点将会逐渐向西部扩展;结合目前的隧道设计与施工技术水平,西部铁路建设过程中将包含大量的长大隧道以及特长隧道,这些隧道中需要铺设越来越多的整体道床,以提高铁路运营的质量以及速度。为此结合以往铁路隧道施工实践,总结了铁路隧道弹性整体道床施工作业流程以及操作要点,可为今后类似工程施工提供借鉴。
The mileage of railway operation in our country has been greatly developed compared with the past. However, the layout of the road network is not balanced, mainly in the central and eastern regions. The focus of construction in the future will gradually expand to the west. Combined with the current tunnel design and construction technology, The construction process will include a large number of large and medium-sized tunnels and extra-large tunnels, in which more and more integrated track beds will need to be laid to improve the quality and speed of railway operations. Based on the practice of railway tunnel construction in the past, this paper summarizes the flexible whole track bed operation process and key points of operation of railway tunnel, which can provide reference for similar projects in the future.
