有砟轨道道砟数量计算软件的开发

摘要

在有砟轨道设计中，道砟数量的计算一直是一个重难点。基于有砟道床断面图，利用 VB 编程软件在界面中输入道床断面参数，通过解析计算精确得到不同线路类型地段的单位长度道砟数量，再经过长度范围统计，得到全线或概算段落的道砟数量，可以极大提高工作效率，为设计和施工提供指导。%In ballast track design,calculating the ballast quantity is always important and difficult.Based on the ballast bed section and utilizing VB programming software,firstly,we entered the parameters of ballast profile on the interface. Secondly,the ballast number of unit length for different line type section was accurately obtained through analytic calcula-tion.Finally,the number of ballast of the whole line or budgetary estimate range was obtained through the statistical range and length.The software could greatly improve work efficiency,and guide the design and construction.
