摘 要: 从三个独立直角坐标系出发,分析公路缓和复曲线点位坐标完整模式,说明缓和复曲线有别于一般缓和曲线的基本关系,指出有效选用连接参数m值在准确计算缓和复曲线完整点位坐标,避免曲线断链的重要作用,结合实例阐述以坐标变换原理计算缓和复曲线点位坐标的公式和应用效果。 In accordance with three independent rectangular coordinate -systems, this paper discusses the complete coordinate formula of the highway spiral curve, and explains its two groups' basic relation that difference to the general spiral curve, and points out the significant intentions for averting chain breaking, that comes from the link parameter m selected to compute the right coordinate of the curve points. Combining the example,this paper explain
