摘要
本文明确指出常用缓和曲线的线形为三次螺旋线，称之为三次抛物线是不确切的．结合我国铁路行车速度发展的目标值，计算了在高速行车条件下的曲线最小半径值及采用常用缓和曲线的长度值，对采用常用缓和曲线的可行性进行了分行．
This paper points out that conventional easement curve(CEC)is third power spiral,the so--called third power parabola is not exact.Then,in accordance with the aim value of the high speed railway development in China,the minimum urve radius and the length of CEC are evaluated'the feasibility of adopting CEC is also analyzed.
