摘要
研究了高速公路缓和曲线长度的确定方法,通过高速公路断面迭加图和超高过渡轨迹图,并研究了超高过渡段内不同的旋转阶段、不同硬路肩宽度和坡度情况下超高值的计算公式,为高速公路超高计算提供了理论依据。
This paper studied the methods of how to calculate the spiral length based on the cross-section superposition graph and super-highness transition graph of the highway. We also studied the formula to calculate the super-highness in various rotating stages, various width and slope of road-shoulder during transitive stage. It provided theory evidence for the calculation of highway super-elevation.
