近年来,随着国内高速铁路的飞速发展,隧道已经成为铁路建设的一个重要组成部分。但是由于铁路隧道比例大、断面大、地质结构复杂,因此增加了工程的施工难度。为了达到铁路隧道工程施工技术的具体要求,加强施工管理,保证工程质量,确保施工安全,通过对国内部分已建和在建铁路大断面隧道的施工总结,并结合实际工作中的一些生产实践,论述了大断面隧道的施工技术特点,作出了深入的分析与探讨,为今后类似施工提供了良好的借鉴。
In recent years, with the rapid development of domestic high-speed railway, tunnels have become an important part of railway construction. However, due to the large proportion of railway tunnels, large cross-sections and complex geological structures, construction difficulty of the project is increased. In order to meet the specific requirements of railway tunnel construction technology, strengthen the construction management, ensure the project quality and ensure the construction safety, through the summary of the construction of some large-section cross-section tunnels under construction and under construction in China and some production practices in practical work, Discusses the construction technology characteristics of large section tunnel, made an in-depth analysis and discussion, which provides a good reference for similar construction in the future.
