北京地铁远期双线换乘站换乘形式分析

随着城市轨道线网规划规模的不断发展,地铁换乘站的数量不断增加。在设计工作中同期或近期换乘站的设计较为深入细致,而线网规划远期换乘站的研究却不够深入,在建地铁站设置的位置及预留换乘形式直接影响着远期换乘站的设置及使用功能。本文分析了双线远期换乘的几种形式及特点,通过对北京地铁5号线蒲黄榆站由于规划相对滞后引起后期改造困难和既有卫星广场站先期站位未充分考虑车站换乘设置,致使后期换乘实施困难,使用功能被削弱的问题进行了简要分析,提出远期换乘站设计应从线网规划、站位选址、换乘节点预留等方面注意的事项。

Analysis on Transfer Modes between Existing Double-track Metro Stations of Beijing Metro with Long-term Metro Stations

As the urban rail transit network continues to expand, the number of transfer Metro stations is increasing. The design of the Metro stations that transfer with the current or short-term Metro stations is in detail, however, due to the lagging of the plan of the Metro networks, the study on the Metro stations that transfer with long-term Metro stations is inadequate. The positions and preserved transfer modes of the current Metro stations have direct influence on the arrangement and functions of long-term transfer stations. In the paper, the types and features of double-track Metro stations that transfer with long-term Metro stations are discussed, and case study is made on Puhuangyu station and Weixingguangchang station of Beijing Metro. It is suggested that, in the design of long-term transfer Metro stations, special attention should be paid to such issues as Metro network planning, Metro station siting and transfer node preservation.
