摘要
以S型曲线为研究对象,对高危路段中S型曲线段事故原因进行分析,详细描述了S型曲线一般超高渐变和全断面超高渐变方法的特点,并针对全断面超高方法,探讨了S型曲线超高渐变过程及超高渐变率和零坡断面位置等计算问题.该计算方法既能保证车辆行驶安全而且也达到了路面美观的效果.
This paper takes the S shape curve as the research object,the cause of accident of S curve segment in high risk section is analyzed,the characteristics of the S shape curve in general and the method of the super high gradient of the whole section are described in detail. And in view of the super high method,the calculation problems of super high gradient process and super high gradient ratio and zero slope section position are discussed.The calculation method can not only guarantee the safety of the vehicles,but also the beauty of the road surface.
