摘　　要：道岔是制约列车运行速度的关键设备。为全面提升城市轨道交通运输效率,提高列车过岔速度,减小地下开挖面积,降低土建工程造价,新研制了60 kg/m钢轨12号对称道岔,可以较好地满足使用要求。本文结合对称道岔的设计,介绍道岔平面线型设计、结构设计、动力学特性分析等关键技术。Turnout is a key equipment constraining the train running speed.A new No.12 symmetrical turnout matching 60 kg/m rail was designed in order to improve transportation eff iciency of urban rail transit,increase turnout passing speed,decease excavation area and reduce construction cost.The turnout can meet the operation requirements greatly.Combined with the design of symmetrical turnout,some key technologies including the horizontal alignment design,structure design and dynamics analysis of turnout were presented.
