摘要
汶川地震对震区公路隧道结构造成了严重的破坏,这严重影响了灾区震后救援和灾后重建。为了保留汶川地震灾区公路隧道震害的珍贵资料,对震区公路隧道震害资料进行了搜集、整理、统计和分析。首先按照隧道结构拱部、边墙、仰拱及附属结构进行统计和分析,再对影响隧道震害的六个因素(震中距、地质条件、断层、竖向地震、支护结构及施工质量)进行了研究,并得出了一些抗震设防启示及建议。研究成果一方面为研究汶川地震震区公路隧道震害机理提供了基础资料,另一方面对于进一步研究高烈度地震区公路隧道抗震及减震技术起到了推动作用。
Highway tunnel structure was seriously damaged in the hit region during Wenchuan Earthquakes.The disaster relief and post-disaster reconstruction were seriously affected.In order to archiere the data of tunnel disaster in Wenchuan seismic disastrous area,we carried out a job to do arrange statistics and analyze the tunnel earthquake disaster data.Firstly,subsection statistics and analysis were in accordance with the tunnel archs,side walls,inverted archs and accessory structures.Secondly,Six influencing factors（epicentral distance,geological condition,faultage,vertical earthquake,supporting structure and construction quality） of tunnel earthquake damage were studied,and some enlightenment and recommendations of earthquake fortification were brought up.On the one hand,the research results provide basic data to study the tunnel earthquake damage mechanism in Wenchuan seismic disastrous area;On the other hand,the research results can promote the further study of earthquake proofing technique and cushion technique in a highly seismic area.
