摘　　要：十字换乘地铁车站预留换乘节点的结构受力复杂,采用有限元程序建立空间计算模型,分析预留换乘车站节点范围的梁、板、柱内力,找到应力集中部位,为设计提供理论依据,保证车站结构的安全。The behavior of the reserved-joint in a crosstransfer station is complicated. By means of an FE space model, the internal forces in girders, colunnms and plates of the reserved-joint structure have been found. The stressconcentration spots that should be reinforced have also been determined, thus providing a theoretical basis for the structure safety design of a subway station.
