山岭隧道震害调查及修复技术研究

Investigation of Mountain Tunnel Earthquake Damage and Study on Remedial Measures

"5.12"汶川地震对都汶公路多座隧道造成了较为严重的破坏。通过对都汶路、绕坝路等15座隧道震后调查、资料收集与分析,提出了隧道震后各种修复措施并分析了其使用效果。浅析了山岭隧道的抗减震原则和措施,对此进行了相应的总结。总体而言隧道震后修复措施起到了良好的效果,对救灾和灾后重建工作起到了积极的作用;同时隧道应从规划、设计阶段采取合理的抗减震措施。

＂5.12＂ Wenchuan Earthquake caused severe damages to tunnels on Dujiangyan-Wenchuan road and Raoba road. According to detailed investigations and data collection and analysis based on the fifteen tunnels located at Dujiangyan-Wenchuan road and Raoba road after the earthquake, this paper proposes several remedial approaches, reviews their effects and puts forward the criterion and the principle about the seismic absorption. Over all, the remedial measures have functioned effectively, and helped the disaster relief and reconstruction. On the other hand, anti seismic absorption action should be taken for the tunnel at the planning and design phase.
