摘要
在缓和曲线较长的情况下,对超高渐变段设置在缓和曲线的不同段落的情况进行了分析,选出最优方案。
In the case that transition curve is longer than the superelevation runoff section, the superelevation run- off section could be setted up in the different position of the transition curve . Each situation will be discussed and the optimal case will be elected.
