Restoration Construction Practice for Daliang Tunnel of Lanzhou-Urumqi High-Speed Railway Under Earthquake Disaster
Earthquake disasters pose significant challenges to the safety of underground railway tunnel structures.Once structures are affected by earthquakes,their safety and stability are greatly compromised.Therefore,timely and effective repair of earthquake damage is crucial for ensuring the safety and stability of railway transportation.Taking the restoration project of the Lanzhou-Urumqi High-speed Railway after the earthquake as an example,this study outlines the basic information of the Menyuan earthquake,analyzes the damage to the Daoliang Tunnel,and proposes a comprehensive plan for arch wall replacement,lining reinforcement,and full reconstruction of damaged sections.Additionally,it summarizes the practical experiences and lessons learned from the project and provides innovative methods for construction methods,project management,and mechanical applications.This study serves as a reference and guidance for future post-disaster recovery efforts.
