摘　　要：南京地铁一号线某车站一、二号线换乘站 ,地铁二号线区间和规划的公路隧道斜交穿过车站地下二层 ,车站节点多 ,结构受力复杂。采用传统的平面简化法显然难以确定车站各种构件受力情况。本文提出采用梁 板 柱空间单元模型 ,利用通用程序ALGOR ,对车站进行空间受力分析 ,并将结构节点处梁、板、柱内力与一般地段进行比较 。A station of Nanjing Metro Line 1 is a transfer station between Metro Line 1 and Metro Line 2. The running tunnel of Metro Line 2 and planned highway tunnel pass through the second story of the underground station. The load on structure with many joints is a complex one. It is difficult to determine the load on structural members by use of classic simplified plane method. This paper puts forward a method by use of beam plate column element model to analyze the spatial load on the metro station with a general program ALGOR and the load on beam, plate, column in the structural joints is compared with that in the general sector, which provides background information of structure design for the metro station.
