摘　　要：在盖挖法或暗挖法施工的地铁车站中,常常采用钢管柱和牛腿形成组合结构来承受主纵梁传递的竖向荷载。本文将利用通用分析软件ANSYS,对钢管柱及主纵梁连接节点进行受力分析,明确各细部的受力特点,并验证结构构件的安全程度。In the subway station construction, the vertical loads transported by the main longitudinal beam are carried by the composite structure consisting of steel pipe pillar and steel movable support. In this paper the bearing capacity of the joiut of steel pipe pillar and longitudinal beam are analyzed with ANSYS. It＇ s hoped that it will provide reference for the design of this kind of structure.
