线路折点参数的计算法

在公路、给排水、水利等工程中，经常会计算线路的转角、桩号、坐标等各参数，文章采用矢量的方法给出了这些参数的计算公式。把这些公式输入到Excel电子表格中，利用电子表格的自动计算功能，很容易把所有的折点参数都计算出来。该法对提高计算的准确性、缩短设计周期有明显的效果，并已在万家寨引黄工程中得到应用。

Calculating Method of Line''''s Break- point Parameters

In highway work, water supply and drainage work and hydraulic work, the line's corner, pile number, coordinate and other parameters are often calculated. Adopting the vectorial method, this paper gives some formulas to calculate these parameters. All break- point parameters can be calculated easily through putting these formulas into Excel tables and utilizing the auto- calculation function of e- tables. The method, which has obvious effect in increasing the accuracy of the calculation and shortening the design periodic time, has been used in Wanjiazhai Yellow River Diversion project.
