坐标法计算线间距及其电算实践

Applying Coordinate Method to Calculate the Distance of Double-Line Railway and its Practice of Code in Visual C^(++)

主要讨论线路平面线间距的计算问题,对传统的坐标法计算有新的思路。并充分注意计算机的发展,在Visual C^(++)集成环境下编程,只需输入Ⅰ线交点坐标、曲线半径、缓和曲线长及Ⅰ、Ⅱ线相对位置、Ⅱ线曲线半径、缓和曲线长等简单要素,即可计算出Ⅱ线交点坐标、Ⅰ、Ⅱ线曲线要素、任意点里程向坐标转化和在直线变距、曲线变距及单绕段等各种情况下的Ⅰ、Ⅱ线线间距,并有很高的计算精度。

This paper developed the traditional coordinate method in calculating distance between double-line railway. Following the computer's development, we made computer code in Visual C++ development environment, in which only some simple elements of double-line railway curves need inputting yet the program output the results of distance between double-line railway which are of extremely high calculation accuracy.
