Study and Formula Deduction about Superelevation Design

提出了超高渐变率过小时超高过渡段的确定方法，推导了Ｓ型曲线的超高过渡计算公式。这些公式可直接应用于工程实践。

This paper presents a method for determining the superelevation transition zone when the transition ratio is too small, and deducts the formula for superelevation design of S—type curve. These formula can be used in engineering.
