单柱地铁车站典型布局特点及结构方案分析

Analysis on Typical Layout Characteristics and Structural Schemes of Single-column Metro Station

目前城市轨道交通地下车站普遍采用单柱双跨箱形框架结构体系,但在结构设计中常遇到车站内部设备或外部地下构筑物与车站结构纵向主梁冲突的情况,造成纵梁局部被中断,并对该部位的结构受力带来较大的不利影响。文章针对上述问题提出了相应的解决方案,并以国内某地铁车站工程设计为背景,对单柱车站结构布置、特殊部位结构设计处理以及分析方法进行了探讨,可供轨道交通设计人员借鉴参考。

At present,the single-column double-span box frame structure system is commonly used in the underground stations of urban rail transit,however,in the structural design,the internal equipment of the station or the external underground structures are often in conflict with the longitudinal main beam of station structure,resulting in the partial interruption of longitudinal beam,and bringing a greater adverse impact on the structural force at that spot.This article proposed corresponding solutions to the above problems,and,with the design of a subway station in China as the background,it discussed the layout of single-column station structure,the structure design treatment of special place,and the analysis methods,which can provide the reference for rail transit designers.
