作为平面线形设计的传统方法,导线法被广泛应用于各级道路设计中,其计算精度和功能也大幅提高,但对一些特殊情况的处理仍不尽人意。针对两交点间需直接生成S型或C型曲线,文章提出了导线法相邻平曲线组合设计模型,在传统单交点平曲线单独设计的基础上,结合模式法将相邻两交点平曲线作为一个整体进行设计计算,使得路线设计更加合理高效。
As the traditional method of planar linear design, the method of lead method is widely used in the design of roads at all levels, and its computational accuracy and function are also greatly improved. However, the handling of some special cases is still not satisfactory. In order to directly generate S-shaped or C-shaped curves between the two points of intersection, the paper proposes a combined design model of adjacent flat curves of wire method. Based on the single design of flat curves of traditional single points, combined with the pattern method, A whole design calculation, making the route design more reasonable and efficient.
