摘要:
针对公路路线传统设计方法的不足,引入了平曲线曲率变化率的概念,根据平曲线曲率变化率与交通事故的关系,提出了车辆行驶稳定性公路平曲线曲率变化率的安全评价标准.根据这一标准,利用高等级公路缓和曲线的设计规范和采动高等级公路允许的极限附加曲率大小,探讨了矿区高等级公路平曲线之圆曲线长度的计算公式.
Abstract:
In view of the shortage of traditional design methods of highway route,the conception of level curvechanging rate of curve was introduced,the safety assessment standard of level curve changing rate of curvewhich can ensure vehicle stability was proposed according to the relationship between level curve changing rateof curve and traffic accident.Based on this safety assessment standard,the formula for the circle curve lengthof high-grade highway level curve in mining area was investigated by using the design specifications of high-grade highway transition curve and the maximum additional curvature caused by mining.
