摘要
以螺旋线为缓和曲线,并根据螺旋线的性质,推导了卵型曲线中间缓和曲线长度的计算公式及中间缓和曲线上任意桩号绝对坐标的计算公式,从而为低等级公路和高等级公路互通立交匝道的测设、施工放样提供捷径。
Based on the property of easement curve, the authors proposed the calculation formulas of middle length of easement for oval curve and the formulas of any station coordinates. It is convient and (accurate) for the alignment design of highway,interchange and construction location.
