摘　　要：通过对现有的直线与线路曲线交点坐标解算方法的分析,结合线路曲线的统一数学模型,给出了直线与线路曲线交点坐标的统一解算模型。实际算例表明,统一模型不仅精度高,适于计算机编程,而且可自动识别和处理单双交点问题,具有广泛的应用前景。Through analyzing the existent methods for solving the intersection point coordinate of straight line and highway curve, combined with the general mathematical model for highway curve, a general solution model for the intersection point coordinate is given. Numerical experiments show that the general solution model for the intersection point coordinate is not only accurate, easy for computer programming, but also can automatically identify and process single-double intersection point problems. Thus it has broad application foreground.
