| 摘 要： | 以杜家山隧道为例,通过对震后杜家山隧道变形破坏特征分析发现杜家山隧道破坏过程具有明显的时效特征,分析得出地震作用是杜家山隧道渐进破坏的外因,岩性条件、区域构造条件、地下水条件是其内因,并在此基础上对隧道渐进破坏机理进行了深入研究。

| Abstract: | Taking Dujiashan tunnel as the research object,based on analyzing deformation and failure characteristics of Dujiashan tunnel,we find that Dujiashan tunnel destruction has an obvious aging characteristic.Through the analysis,we get the conclusion that the earthquake is the external cause to the progressive failure mechanism in Dujiashan tunnel.The stratum,lithology,regional structure,groundwater are the internal causes.On this basis,we have made a further research on the progressive failure mechanism of the tunnel,which will have important theoretical value and practical construction meaning to protection and tunnel collapse treatment. |
