摘要: 在目前的地铁地下车站设计中,单元模型为主要模拟计算方式,采用单元模型以及整体模型两种计算方式。通过对其难点边界条件的确认,对其受力状态进行模拟计算,并对其计算结果对比分析,发现二者结果相差基本在5%内,但考虑整体模型更接近实际情况,建议在地下车站模拟计算中采用整体模拟计算方法。对地下车站设计人员具有一定的参考价值,在设计过程中可起到一定的指导作用。

Abstract: The unit model is the main analytical model in the design of the subway stations. This paper discusses both the unit model and the global model in the subway design through the appropriate defining the boundary conditions in both model. The analytical results indicate that the differences between two models are within 5% but the global model is closer to the real conditions. It is therefore suggested that the global model be used in the subway station design.
