摘要
分析决定公路平面缓和曲线长度及参数的主要因素。阐述缓和曲线设计不仅要满足离心加速度变化率、司机操作反应时间、超高渐变率、视觉条件等要求,还要兼顾到地形、地物、排水及与所夹圆曲线组合等方面。
The design of transition curve should meet the requirements such as the rate of change of centrifugal acceleration, the driver reaction time,the rate of ultra-high gradient and visual conditions.It also takes into account the topography,surface features,drainage and the connected circular curve
