公路与城市道路圆曲线超高设计相关规范对比分析

The comparative analysis of circular curve superelevation design in relevant specification for highway and urban road

公路与城市道路的圆曲线超高设计相关规范中规定不同,通过对比其规定并研究分析,提出公路不设超高的圆曲线最小半径宜适当缩小,最大超高值建议取6%,平曲线极限最小半径宜适当增大。

The rules of circular curve superelevation design in highway and urban road specification are different,through the comparative analysis of the rules,the minimum radius of circular curve of no superelevation for highway should be appropriately reduced,the maximum superelevation value should be 6%,the ultimate minimum radius of horizontal curve should be appropriately increased.
