研究目的:地铁车辆段是地铁列车的停车、保养、维护及检修基地，列车清洗是地铁车辆段最重要的功能 之一。目前地铁车辆段普遍采用了自动化机械洗车机以提高洗车效率和清洗质量，设置有独立的洗车线。洗 车线不同的布置型式对洗车能力和效率影响很大，因此在车辆段设计中如何分析洗车能力、优化洗车线布置 是值得研究的重要课题。
研究方法:通过对广州地铁及上海地铁车辆段几种典型的洗车线布置型式进行洗车工艺比较和洗车能 力分析，研究各方案的适用性及相应能力。
研究结论:不同的洗车线布置型式对洗车能力和效率影响很大，选择顺序建议为:咽喉区通过式布置型 式、运用库并列通过式布置型式、咽喉区八字线通过式布置型式、尽头线往复式布置型式
Research purposes: Metro depot is the base of train parking maintenance and overhaul. The train washing is one of the most important functions of metro depot. At present } train automatic washing devices are used widely to improve the washing quality and efficiency and the special washing tracks are set in the metro depot. As the different layout type of train washing track has a great effect on the washing capacity and efficiency，how to analyze washing capacity and optimize the layout of washing track in the depot design is an important research subject worthy to be studied.
Research methods: By comparing the washing technology and analyzing washing capacity of several typical layout types of train washing tracks in Guangzhou and Shanghai metro depots，this paper studies the applicability and corresponding capability of various schemes.
Research conclusions: As the different layout type of train washing track has a great effect on the washing capacity and efficiency the choosing sequence is suggested as scheme 1，scheme2，scheme3 and scheme4.
