摘要
轻轨系统作为一种中运量的城市轨道交通系统具有广阔的应用空间,轻轨线路的平面曲线半径对线路的适用性、投资大小、换乘方便程度、施工难易程度、旅客乘坐的舒适性以及养护维修工作量等均有重要影响,因此选择合适的平面最小曲线半径具有重要意义。结合轻轨线路的特点,分析确定线路平面最小曲线半径的基本原理,讨论影响线路平面曲线半径大小的主要因素,对轻轨线路合理的平面最小曲线半径进行探讨。
The light rail system features a medium transport capacity in urban rail transit and has broad application space.The plane curve radius of light rail lines has an important effect on the applicability of lines,investment size,transfer convenience,ease of construction,comfort of passengers and maintenance workload,so it is very important to select the appropriate minimum plane curve radius.At present,light rail lines mostly refer to Code for Design of Metro（GB 50157—2003） for design and construction,which cannot give full play to the advantages of light rail lines.Considering the characteristics of light rail lines,authors of the paper analyzed the principles of minimum plane curve radius,specifically analyzed the main influencing factors of plane curve radius,and researched the reasonable minimum plane curve radius of light rail lines.
