摘要
随着高速公路和高速铁路的不断发展,仅以回旋线作为单一的缓和曲线已不能完全满足实际需要,必然需要补充一些高次曲线或其它类型的曲率渐变曲线。文中总结出各种类型缓和曲线的任意点坐标计算级数法展开的通用方法和切线迭代法反算各种类型缓和曲线里程的方法,通过设计勘测设计应用系统,进行实际应用,证明了其实用性和可靠性。
With constant development of highways and high-speed railways, using only the clothoid as single transition curve has not already been able to meet actual requirements completely, so it is necessary to add some high-order curves or other types of transition curves with gradual change curvature. In the paper, a general algorithm of expansion in series when the coordinate calculation of arbitrary point on various types of transition curves is made and the method using the tangent iterative method to calculate inversely mileage of different types of transition curves are summarized, which are proved to be practical and reliable through actual practice of developing the survey and design application system.
