站台屏蔽门在地铁热环境控制中的经济性分析

Economic Analysis for Platform Screen Door in Subway Thermal Environment Control

热环境分析是地铁筹建中的一个重要课题，而地铁站台是否采用屏蔽门又必须从经济和技术等各方面去综合评价。本文论述了影响地铁环控系统初投资和运行费用的因素，并结合实际工程对站台屏蔽门方案进行了技术经济分析。

Subway thermal environment analysis is very important for subway system design and construction.Whether platform screen doors are installed in subway station should be decided through technical economic analysis.This paper discusses the factors effecting first cost and operation cost of subway environment control system,and gives technical economic analysis by means of computer dynamic simulation on platform screen door for subway design and construction projects.
