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