本刊在1978年第2期上发表了“站场曲线间距计算公式”一文后,陆续收到一些有关站场曲线间距计算的稿件,现摘要选登以下几篇,供读者参考。关于站场曲线间距计算方法,可用三角法,可用解析几何法,也可利用曲线交点座标进行计算等。其精度的高低和计算速度的快慢,既取决于公式的严密性,也要凭计算者技术的熟练程度和习惯上所采用的计算法而定。所以,对于站场曲线间距的计算,应结合具体情况,有多种计算法以供选择,灵活应用,以利于设计。
In the second issue of the 1978 issue of this article, the “Station Formula Curve Spacing Formula” was published. Afterwards, some manuscripts about the calculation of the spacing between station and station curves were received one after another. The current abstract was selected for the reader’s reference. With regard to the method for calculating the spacing between station and station curves, a trigonometric method may be used, an analytical geometry method may be used, and a curve intersection coordinate may be used for calculation. The level of accuracy and the speed of calculations depend not only on the rigor of the formula, but also on the proficiency of the computer operator and the calculation methods used in practice. Therefore, for the calculation of the distance between the station and the curvilinear curve, a variety of calculation methods should be selected for the specific circumstances and be applied flexibly to facilitate the design.
