Ltd.10.26689/jard.v9i1.9494ArticleAnalysis of Reinforcement Techniques for Newly Built Tunnel Defectshttps://artdesignp.com/journal/JARD/9/1/10.26689/jard.v9i1.9494WeiYike2025912025-02-10Newly built tunnels often encounter a series of defects within the first few years of operation. If not promptly addressed and reinforced, these defects threaten the tunnel’s durability and stability and bring severe challenges to its safe operation. This study aims to explore reinforcement techniques for addressing defects in newly built tunnels. The research begins with an analysis of common defects found in newly built tunnels, followed by a case study of the Jinfeng Tunnel in Chongqing, examining the post-construction defects. The actual reinforcement strategies and methods employed for the tunnel are then discussed. Finally, based on the research findings, this study provides insights and references for tunnel operation and construction units in China, aiming to enhance the overall quality of tunnel engineering in the country, align with sustainable development goals, and promote further improvements at a macro level.
