北京地铁6号线五路居站道岔型号及折返能力分析

列车在车站的折返能力,是决定系统能否实现最大通过能力的关键因素之一。北京地铁6号线远期最大通过能力为30对/h,列车采用B型车8辆编组,列车长度160 m。起点五路居站受车站站位工程条件的限制,在站前设交叉渡线,列车通过站前交叉渡线折返。为了保证五路居站的折返能力,对站前交叉渡线采用12号道岔和常规9号道岔两种方案,从折返能力、工程规模、检修等方面进行综合分析、比较,分析各自的优缺点,给相关工程提供借鉴。

Analysis on Turnout Model and Turn-back Ability of Wuluju Station of Beijing Metro Line 6

The turn-back ability of the trains at station is one of the critical factors which determine whether the maximum carrying capacity of the metro system can be achieved.In Beijing Metro line 6,the maximum carrying capacity in the long term will be 30 pairs of trains per hour,and one train with the length of 160 m will consists of 8 B-type cars.Wuluju Station,which is the origin station of Beijing Metro line 6,is restricted by engineering conditions,so the scissors crossing are set up in front of Wuluju Station,and the trains will turn back through the scissors crossing.In order to ensure the turn-back ability of Wuluju Station,two turnout schemes including the turnout No.12 and the conventional turnout No.9 are adopted in the scissors crossing in front of the station.Then the analysis and comparison of advantages and disadvantages on the two schemes are provided in this article,from the turn-back ability,project scale,maintenance requirement and other aspects.The analysis and comparison are hoped to provide a reference for other similar projects.
