摘要
国内大城市的首批城市轨道交通线路大多建设于2005年前后,未来5~10年内将普遍到达信号大修年限,在大修中同步进行制式改造以满足线路的运能需求是普遍的做法。既有线路的大修与新线建设的差异较大,在国内普遍缺少大修改造的经验。通过结合上海轨道交通2号线CBTC(基于通信的列车控制)信号系统改造的实际案例,对既有线路信号系统大修改造类项目的典型难点进行研究。将信号大修的典型难点分为3种类型,研究其应对策略,以期为后续其他城市陆续开展的信号大修提供借鉴。
The first batch of urban rail transit lines in domestic big cities were mostly built around 2005.In the next 5-10 years,they will generally reach the overhaul period.It is a common practice to carry out system transformation to meet the transport capacity demand during the overhaul.This kind of project differs greatly from new line construction,and is generally lack of experience in China.Taking the actual case of CBTC signaling system transformation of Shanghai Rail Transit Line 2,the typical difficulties of large-scale transformation project of existing line signaling system are studied.The typical difficulties of signaling overhaul are categorized into three types,and their coping strategies are studied in order to provide reference for subsequent signaling overhaul in other cities.
