摘要
分析了公路隧道衬砌背后空洞的危害和原因,采用平面弹塑性分析模型,并运用有限元软件"同济曙光GeoF-BA"分析研究了不同情况下的衬砌背后空洞对衬砌结构内力的影响,从而更好地对隧道病害进行整治。
This paper analyzes the causes and hazard of empty areas behind lining in highway tunnel, and studies its influences on internal force of lining structure using plane elastoplastic analysis model and finite element software "Tongji exposure Geo FBA", in order to better treat tunnel failures.
