【摘要】：随着世界及中国高速铁路的迅猛发展以及中国高铁建设重心的逐步西移,隧道在高铁建设中所占的比例将越来越大。在高速铁路隧道施工中,二次衬砌出现裂缝的情况已经越发频繁,严重威胁着高速铁路的质量和安全,给高速铁路的运营埋下了不可估量的隐患。为了保证高速铁路隧道的施工质量、外观形象、结构安全,本文以内陆某高速铁路隧道为例,定性分析了隧道内的二次衬砌所产生的裂缝,依此为依据对裂缝的发育状况进行了详细的观测,进而对高速铁路隧道二次衬砌的裂缝提出了预防控制及整治措施,并在所研究隧道中对裂缝整治方案进行了验证和改进,以期能够为后续类似的高速铁路隧道工程施工提供参考。
[Abstract]:With the rapid development of high-speed railway in the world and China and the gradual shift of the center of gravity of high-speed railway construction in China, the proportion of tunnel in the construction of high-speed railway will become larger and larger. In the construction of high-speed railway tunnel, the secondary lining cracks have become more and more frequent, which seriously threaten the quality and safety of high-speed railway, and bury inestimable hidden dangers to the operation of high-speed railway. In order to ensure the construction quality, appearance and structure safety of high-speed railway tunnel, this paper takes a inland high-speed railway tunnel as an example to qualitatively analyze the cracks produced by the secondary lining in the tunnel. According to this, the development of cracks is observed in detail, and the preventive control and regulation measures are put forward for the cracks of secondary lining of high-speed railway tunnel, and the crack regulation scheme is verified and improved in the studied tunnel. In order to provide a reference for the construction of similar high-speed railway tunnel engineering.
