摘要:
线路设计时，采用正确的缓和曲线线形是保证列车安全平稳运行的关键。缓和曲线线形的选择应重视交通类型及运行条件。本文从线形方程特征参数、轨道动力特性和线路测设计算等方面，对三次抛物线和回旋线用作缓和曲线的适用性进行对比分析。研究结果表明，铁路等轮轨轨道交通中，缓和曲线不能用回旋线简单替代三次抛物线。最后，提出了三次抛物线设计参数的具体确定方法，为铁路线路设计、轨道施工和后期养护维修提供技术指导。
Abstract:
The correct transition curve alignment selected during track design is the key to ensuring the safe and stable operation of the train. The selection of transition curve alignment shall take into account the type of traffic and operation conditions. In this paper，the applicability of using the cubic parabola and clothoid as transition curves were compared and analyzed from the aspects of characteristic parameters of alignment equation，dynamic characteristics of the track，and design calculation of alignment. The results show that for the transition curve，the cubic parabola cannot be simply replaced with the clothoid in the rail transit of wheel-rail such as railway. Finally，the method of determining the design parameters of the cubic parabola is put forward to provide technical guidance for railway track design，track construction，and later maintenance.
