北京地铁19号线平安里换乘站建筑方案设计

Architectural Design Proposal for Beijing Subway Line 19 Ping’anli Interchange Station

[目的]由于城市轨道交通换乘站规模较大,受周边环境制约因素较多,以及车站建筑设计难度较大,因此需对其进行科学合理的设计。[方法]以北京地铁19号线(以下简称“19号线”)平安里换乘站建筑方案设计为例,从规划需求、现状条件、文物及环境保护需求、资源节约需求及其他控制因素对该换乘站建筑方案设计控制条件进行了分析。研究出该换乘站建筑方案设计中针对站位、站型、规模及其他控制因素等重难点问题的解决思路。提出了平安里换乘站的最终布置方案,并简述了该换乘站的设计原则与设计关键点。[结果及结论]平安里换乘站的最终布置方案如下:19号线平安里站位于赵登禹路与平安里西大街交叉口北侧,其主体采用地下两层岛式双层双柱三跨结构,地下一层为站厅层,地下二层为站台层。车站东南侧外挂用房为地下三层,换乘通道设置于地下二层,连通19号线与6号线。车站设置3个出入口,2个安全出口,1个无障碍电梯,2组风亭及1组冷却塔。

[Objective]Given the large scale of urban rail transit interchange stations,numerous environmental constraints,and the significant difficulties in station architectural design,it is necessary to conduct a scientific and rational design for interchange stations.[Method]Using the architectural design proposal for Beijing Subway Line 19 Ping’anli Interchange Station as example,the design control conditions for the interchange station are analyzed from various aspects,including planning requirements,current conditions,heritage and environmental protection needs,resource conservation demands,and other controlling factors.Solution ideas for challenging issues regarding station location,station type,scale,and other controlling factors in the architectural design proposal for the interchange station are studied.The final layout plan for Ping’anli Interchange Station is proposed,along with a summary of the design principle and key design points.[Result&Conclusion]The final layout plan for Ping’anli Interchange Station is as follows:Line 19 Ping’anli Station is located north of the intersection of Zhaodengyu Road and Ping’anli West Street.The main structure adopts a double-level island platform with a two-storey,double-column,and three-span structure.The first underground level serves as the concourse,and the second underground level is the platform.An ancillary building on the southeast side of the station has three underground floors,with an interchange passage on the second underground level connecting Line 19 and Line 6.The station has three entrances,two emergency exists,one accessible elevator,two ventilation shafts,and one cooling tower.
