摘　　要： 西安北站主站房高架层的平面尺寸达522.38m×182.5m,对温度作用进行了详细分析,并采用m法模拟土体弹簧刚度。通过在高架层设置滑移缝,在高架层长楼梯支座下设置滑动构造等,较好地解决了结构超长问题。钢桁架与柱节点采用外环板形式。屋盖为大跨度、大悬挑的三向交叉网格结构,在树形柱节点中采用了向心关节轴承。 The overhead layer in the main building of Xi＇an North Railway Station has large plan dimensions with 522.38m×182.5m.Temperature action was analyzed in details,and m method was adopted to simulate soil springs stiffness.Slide rifts and slide constructions under long stairs are used in the overhead layer,and so on.All these measures are taken to solve the problem that the structure is super long.Outer ring plates are applied in the nodes between columns and steel trusses.The roof is a three-dimension grid frame with long span and long cantilever.Radial spherical plain bearings are employed in tree columns.
