高速铁路隧道二衬质量缺陷整治措施研究

Research on Remediation Measures for Quality Defects of Secondary Lining in High-speed Railway Tunnels

高速铁路隧道质量缺陷已经成为影响高铁运营安全的突出问题,工程交付运营后,在天窗时间内,质量缺陷整治作业存在效率低、难度大、克缺费用高等特点。文章以西南地区在建的7座高速铁路隧道二衬施工过程中存在的质量缺陷为研究对象,分析了影响隧道使用功能和运营安全的主要缺陷的原因,并提出整治措施,旨在为隧道二衬质量缺陷整治提供参考。

The quality defects in high-speed railway tunnel have become a prominent problem affecting the safety of high-speed railway operation.After the engineering is delivered and put into operation,the quality defect remediation work has the characteristics of low efficiency,high difficulty and high cost in the skylight time.Taking the quality defects existing in the secondary lining construction of seven high-speed railway tunnels under construction in Southwest China as the research object,this paper analyzes the causes of the main defects affecting the use function and operation safety of the tunnel,and puts forward remediation measures,aiming to provide reference for the remediation of tunnel secondary lining quality defects.
