据中国城市轨道交通协会统计,2013年末,中国累计有19个城市建成投运城轨线路87条,运营里程2539公里。其中以北京、上海、广州等大城市为主导,特别是首都北京的地下铁路,虽然已开通了17条线路之多(至2013年底),但因出行的人流量巨大,还是人满为患,运输压力很大,这种情况下安全性就更显得格外重要。本文将从工程建设的角度谈谈轨道交通的安防系统建设。 According to the statistics of China’s Urban Rail Transit Association, at the end of 2013, a total of 19 cities in China were completed and put into operation with 87 lines of urban rail lines, with an operating mileage of 2539 kilometers. Among them, major cities such as Beijing, Shanghai and Guangzhou dominate, especially in the capital city of Beijing. Although 17 lines have been opened (by the end of 2013), the traffic volume is huge and overcrowded, and traffic pressure is very heavy Large, in this case the security is even more important. This article will talk about the construction of rail transit security system from the perspective of engineering construction.
