摘要
以JTG B01-2003公路工程技术标准为基础,推算出曲线半径和超高横坡值的二次抛物线关系式,分析了平曲线超高横坡、横向力系数与安全性、舒适性的关系,提出了超高设计的几点建议。
Based on the JTG B01-2003 highway engineering standard, the second-degree parabola relation between curve radius and super cross slope value was calculated. The relationship between curve super cross slope, cornering ration and safety, amenity was analyzed, and ,several suggestions about super elevation design were proposed.
