摘要
针对工程测量工作中直线与曲线交点坐标解算问题,首先分析了现有解算方法存在的不足之处,然后通过以数值积分方法建立曲线统一参数方程,给出了用逼近法、迭代法、二分法求解该问题的具体数学处理方法,并在卡西欧fx-4800p计算器上编程实现,还结合实际工程给出了算例。实际工程应用表明,该文所述算法是解算该问题较好方法。
To solve the intersection point coordinate problem of straight line and curve in engineering surveing, the paper analyzed the shortage of existent methods, then gave the specific mathematic solving methods： approaching.iteration and bisection through establishing curve parameters equations based on numerical integraction method. The Casio fx-4800p computer program and the example are also given respectively. The engineering applications showed that these methods are better algorithms.
