研究结论:(1)建立了隧道结构震害评价等级，主要包括隧道震害程度分级原则、钢筋混凝土和素混凝土二次衬砌震害等级评价以及抢通、保通和恢复重建三阶段震害处治重点;(2)明确了抢通、保通和恢复重建三阶段隧道衬砌结构震害处治技术;(3)汶川地震灾区震后运用隧道结构震害评价等级及处治技术进行恢复重建，达到了恢复重建的目标，使震区隧道恢复或超过震前的运营及抗震水平;(4)研究成果可为震区隧道震害修复及抗震结构设计提供参考。

Research conclusions:(1)Established the evaluation grade of seismic damage of tunnel structure，mainly including the graded principles of the seismic damage degree of the tunnels，the evaluation grade of seismic damage of reinforced concrete and plain concrete secondary lining, and the treatment key point of seismic damage of the three stages，the first aid repair stage，ensure access stage，restoration and reconstruction stage.(2)Clarified the disposal technologies of seismic damage of tunnel lining structure of three stages，the first aid repair stage，ensure access stage，restoration and reconstruction stage.(3)The disaster area in Wenchuan earthquake used the evaluation grade of seismic damage and disposal technologies of tunnel structure for restoration and reconstruction after the earthquake，reached the goal of restoration and reconstruction，which recovered or over the level of operation and earthquake-resistant of the tunnels in the earthquake zone before earthquakes.(4)The research results can provide a reference for the repair of seismic damage of the tunnels in the earthquake zone and aseismic design of tunnel structure.
