上海浦东机场旅客捷运系统关键技术

上海浦东机场旅客捷运(MRT)系统采用的是钢轮钢轨A型车,不同于目前机场常用的APM(自动旅客运输)系统,其建设有一些独特之处。重点介绍了浦东机场MRT系统中的信号系统、轨道结构、集约用地设计和精细化建设管理方面采用的一系列关键技术。浦东机场MRT系统的信号系统具有满足全天候运行、区分不同流程客流、有限距离精准进站等技术特点,其轨道结构采用了超大线间距道岔区钢弹簧浮置板、新型液压缓冲式车挡和超薄道床等技术。

Key Technology of MRT at Shanghai Pudong International Airport

The steel wheel and rail type A cars are adopted in MRT(Mass Rapid Transit)system of Shanghai Pudong Airport.Different from APM(Automated People Mover)system that is commonly applied in airports nowadays,the construction of MRT possesses unique features.A series of key technologies used in the signal system,track structure,intensive land use design and delicacy construction management of Pudong Airport MRT system were emphatically introduced.The signal system of Pudong Airport MRT system has technical characteristics such as adaptive round-the-clock operation,distinguishing different categories of passengers,and the train accurately arriving at station within safety distance limitation.The track structure adopts technologies such as steel spring floating slab in turnout area with extra large line space,new hydraulic stop buffer,and ultra-thin track bed.
