【摘要】 以上海地铁明珠线二期上体场站工程的实际施工为背景,对上体场站穿越段施工全过程进行三维有限元分析,动态模拟了施工过程对地铁一号线底板、高架立柱等周围环境的变形影响。得出了一些规律性的认识和有价值的结论,给施工提出了一些有益的建议。更多还原

【Abstract】 Based on the background of actual construction of Shanghai stadium station project of pearl line phase Ⅱ, 3D finite element method is used to simulate the whole process of construction of transverse section of the station. The surroundings influence due to the construction is simulated dynamically with the process of construction, and the knowledge of the rule is gained and valuable conclusions are drawn and some helpful suggestions are made for the safe construction.更多还原
