摘要
超高设计影响因素较多,具有一定的路段差异性,在阐述超高值与行车安全关系的基础上,分析了各超高设计要素及其影响因素,并结合实例说明超高灵活性设计的思路。
Highway superelevation on curved sections is effected by many factors and has the design diversity. This paper elaborated detailedly the relation between the superelevation value and vehicle stability on curved sections, and analyzed the superelevation elements＂ factors in practical design. Eventually, this paper expatiated on the flexibility design method by a superelevation design example.
