摘要
讨论山岭重丘区公路及互通立交匝道设计中非对称缓和平曲线的应用,在平曲线计算的基础上推导非对称缓和平曲线几何要素的计算公式,提出非对称缓和平曲线任意点坐标及方位角的计算方法。
The paper discusses about the application of the horizontal curve of the asymmetrical spiral curve used in the design of highway and ramps for interchange,gives the formula of geometrical elements of the asymmetrical spiral curve on basis of the calculation of horizontal curve and it also states the coordination and the oriental angle calculation method of the asymmetrical spiral curve.
