摘要
基于线路曲线任一点切线方位角计算通式,推出了线路中边桩坐标计算的积分通用公式;借助于复合Simpson公式,给出了线路中边桩坐标计算的通用数值模型,并详细讨论了积分区间等分数n的取值问题。通用模型的建立,为线路中边桩的极坐标测设法奠定了坚实的基础。
Based on the general formula for computing the azimuth angle of tangent line of random point in high way,this paper derives the general integral ones for computing the coordinates of middle and side stakes.According to the compound simpson formula,the general numerical models for calculat-ing coordinates of middle and side stakes are given,and the problem about determining the n,the num-ber for equal-dividing the integral interval in using compound simpson formula,is also discussed.The general models established herein lay the foun dation for the middle and side stakes layout of high way by polar method.
