地铁工程供电系统造价指标分析与建议

在城市地铁建设中，供电系统是工程建设的重要组成部分，其造价直接影响到整条地铁线路的投资。为此在收集国内几个主要城市地铁建设资料的基础上，对地铁供电系统每正线公里造价、接触网和接触轨每条公里造价、地下站和高架站动力照明每平方米造价、区间动力照明每正线公里造价进行分析与对比，由此提出今后在开展地铁供电系统设计时采用造价指标的参考建议。

Analysis and Suggestions of the Subway Engineering Power Supply System Cost Index

In the urban subway construction, power supply system is the important part of the construction project. The construction cost directly influence the whole metro lines investment. Therefore, based on collecting the subway construction material in several major cities, the power supply system cost per kilometer, cat- enary and contact rail per kilometer, underground stations and elevated station power lighting cost per square meter are compared and analyzed. Through which the reference suggestions of using cost index in subway power supply system design period are put forward.
