| 摘 要： | 针对北京地铁五号线北新桥车站基坑工程和其内既有盾构隧道的相互作用机理问题,应用三维有限元程序对基坑工程在多种工况下的施工进行了数值计算,得出施工过程中车站的围护结构、其周围土体及既有盾构隧道的应力、应变及位移结果。通过分析认为,在既有盾构隧道基础上修建大型地铁车站是可行的,并对其他相似工程具有指导意义。

| Abstract: | To research the crosscorrelation between the deep excavation and existing shield tunnel, 3D FEM was used to compute and analyze constructions of metro-station excavation engineering under some kinds of conditions. It educed the results of stress, strain and displacement of shoring structure, soil and existing shield tunnel. According to the results, it concluded that it is practicable that building large scale metro-station based on existing shield tunnel and there is a great significance to conduct other similar engineerings. |
