Based on the specific situation in the process of computing the superelevation transition the horizontal curve of highway, this article gives the universal calculation for the superelevation transition within the superelevation run\|off, conforming to the requirments in Specification for Design of Highway Alignment.

根据在公路设计中平曲线超高过渡计算时遇到的具体情况 ,按照《公路路线设计规范》的要求 ,推导出超高缓和段内超高过渡的通用算法 ,并提出了对“C型曲线”在两回旋线衔接处进行超高、加宽过渡的改进方

Presently the method of roadway superelevation transition(run-off) is not stipulated clearly in the Highway Route Design Specification in China.

我国《公路路线设计规范》对超高缓和段的设计方式没有明确规定,工程实践中超高过渡大多是在缓和曲线上进行。

With regard to the setup of road superelevation,this paper proposed that the superhigh values be rationally decided on in accordance with the requirements upon horizontal force coefficient,road longitudinal gradient and curve location,and illustrated the relationship between them and clothoid and widening transitory section by calculating the length of superhigh transition section.

对于道路超高设置,指出应根据横向力系数、道路纵坡、曲线所处位置等几方面的要求合理选定超高值,并通过超高过渡段长度的计算说明了其与回旋线、加宽过渡段的关系。
