【摘要】 汶川5.12地震给龙门山地区及四川盆地西缘地区带来了大量的房屋倒塌和人员伤亡,也使震区公路交通基础设施遭受巨大破坏。中国政府从防灾减灾的角度提出了"生命线路网"的概念并以此指导震区公路交通的恢复重建工作。为了防止悲剧重演,通过分析震区地质构造、主震破裂特征及震区孕震形势等地质背景,辅以震区交通基础设施破坏模式调查与分析,认为地质学理论在"生命线路网"建设中具有重要作用,并据此提出震区交通恢复重建策略以供参考。更多还原

【Abstract】 On 12 May 2008,the devastating magnitude 8.0(Wenchuan) earthquake struck Longmen Shan region and the western edge of the Sichuan basin,collapsing buildings and killing thousand of people in major cities located in seismic zones.Owing to such a large-magnitude earthqhake,the traffic infrastructures were also destroyed heavily,especially the bridge structurs in earthquake areas.The concept of emergency road network was stated in the disaster prevention and mitigation perspective by Chinese Government,and ought to be always emphasized in the course of rebuilding of transportation in seismic zones.By analysing tectonics of the seismic zones,the character of main rupture plane and potential seismic zones,which were assisted by investigation and analysis on failure mode of traffic infrastructures,it is concluded that geology theories should have had a more significance for construction of emergency road network,and rebuilding strategy hereby is proposed,with the aim to avoid tragedy in the future.更多还原
