地下工程与建筑工程结合的结构体系正朝着复杂化、多样化方向发展。结合上海长江路越江隧道浦西管理中心大楼段复杂结构的设计特点,采用有限元空间计算模型,对基坑围护结构体系的设计、底板下桩基布置原则、隧道匝道与主线的穿越及合并的结构形式转换等,进行了结构合理性分析及受力分析。这为类似复杂的工程结构设计提供参考。 The structural system that combines underground engineering and construction engineering is moving toward complexity and diversification. Combined with the design features of the complex structure of the section of Puxi Management Center of Shanghai Changjiang Road Crossing River Tunnel, the finite element space calculation model is used to design the retaining structure system of foundation pit, the principle of pile foundation under the floor, the crossing of the ramp and the main line and the merger Structural transformation, etc., carried out structural rationality analysis and stress analysis. This provides a reference for similar complex engineering structure design.
