关于缓和曲线可侵入站台范围长度的初步研究

Research on the Length of the Transition Curve that Can Invade in the Platform

针对缓和曲线侵入站台的情况,对缓和曲线可侵入站台范围长度进行分析与研究,探讨控制影响可侵入长度的因素,通过规划求解对各离散点参数进行函数分析,给出缓和曲线可侵入站台范围长度的初步分析结论。

With the increasing maturity of urban development, the design of metro line in urban centers often encounter poor conditions, when the curve is set to the ends of the station, there will be a situation that transition curves invade into the platform. For the maximum length that the transition curve can invade into the platform, there is no stipulation in the ＂Code for design of metro＂. This paper make a preliminary analysis on the influencing factors and the length of the transition curve that can invade into the platform.
