Research on Superelevation Design Method for Suburban Highway Based on Travelling Speed

通过研究市郊公路超高设置的特殊性,基于运行速度,综合考虑了横向力系数后,提出了市郊公路一般最小半径取值、最大超高横坡度的确定以及超高相关参数的取值和调整,并基于运行速度进行超高检验。结合实例对市郊公路超高基于运行速度进行了检验分析,并提出了改善建议,可为类似市郊公路项目超高设计提供参考。

Through the research on the particularity of superelevation setting of suburban highway, based on the travelling speed, the determination of ordinary minimum radius value and maximum superelevation transverse slope of suburban highway and value and adjustment of relevant superelevation parameters are put forward after comprehensively considering the lateral force coefficient and the inspection on superelevation is performed based on the travelling speed. In combination with the living example, the check analysis on the superelevation of suburban highway is made based on the travelling speed, and improvement suggestions are put forward, so as to provide reference for the superelevation design for the similar suburban highway project.
