摘要
本文根据线路曲线元任意点的曲率公式,推导出任意点的切线方位角计算通式,从而导出线路中边桩坐标计算的积分公式。利用CASIOFX-4800P计算器的积分程序功能,进行任意桩号的中边桩坐标计算,从而实现放样计算的连续性,极大地便利了外业工作。
Based on the general formula for calculating the curve of any point in highway, this article derives general one for computing the azimuth angle of tangent line. So the ordinary integral formulae for calculating coordinates of centered and side stakes are given. With the integral function of CASIOfx - 4800p calculator, the coordinates of those stakes of discretional point are calculated. The calculation for setting - out is continuous, which is very convenient to field work.
