中心城区复杂环境下轨道交通车站建筑设计方案研究

Research on Design Scheme of Rail Transit Station in Complex Environment of Central District

本文结合北京地铁14号线望京南站这一典型的中心城区复杂环境下的轨道交通车站作为研究背景。设计上通过设置大量外挂设备用房压缩车站长度、根据客流预测设置非对称侧式站台、左右线非对称楼扶梯组布置、设置双层风道等手段,降低了车站前后区间穿越桥桩、地下室风险、保证道路交通顺畅、避让水源井、保护市政管线等一系列问题,并取得了良好的效益。

This paper takes Wangjing South Railway Station of Beijing Metro Line 14 as the research background,which is a typical metro station in the complex environment of the central district.Design solves a series of problems,such as reduces the risk of crossing bridge piles and basement in the front and rear tunnel of station,ensuring smooth road traffic,avoiding water wells and protecting municipal pipelines,by set up a large number of external equipment rooms to compress the length of the station,set up the asymmetric side platform according to passenger flow forecast,set up the different escalator group of left and right paltform,set up double-deck air duct,and it has achieves good benefits.
