一种线间距的获取方法

METHOD FOR FINDING OUT DISTANCES BETWEEN RAILWAY TRACKS

本文说明利用高级语言编程计算平面资料及里程点坐标，形成结果文件，并利用ＡｕｔｏＣＡＤ软件从结果文件中读取自动绘图数据，绘出只有线型的线路平面图，并从里程点作法线，用鼠标捕捉法线与股道的交点，一次得到一个里程点对应的几个股道的线间距。因此，对于计算点多及复杂曲线地段有很大方便。

The paper explains as following aspects. By applying the high level language programming for calculating the plane data and the coordinates of the mileage points, a resultant statement may be accomplished.By appplying AutoCAD software for taking auto map making data,a plan of railway tracks with only track lines may be plotted. Finally,drawing a normal line from the mileage point,the intersecting points of normal line with track lines may be found out by the mark scanning ,and the distances between several track lines corresponding to a certain mileage point may be obtained at one time . Therfore,it is very convenient for the sections with plenty calculating points and complx curves.
