路基半断面面积公式和体积积分公式

A New Method of Half Sectional Area Calculation and Volume Integral

以铁道线路路基半断面为模型,建立了横断面面积的计算公式,又经过积分,导出了路基土石方工程数量的体积积分公式。该方法思路独特,公式简单,既可以用面积公式按传统的平均断面法或平均距离法粗略计算土石方数量,又可以用体积积分公式对路基土石方作精确计算.以适应不同设计阶段的精度要求:既适用于手工计算,又适合于计算机编程和计算机辅助选线使用。

Based on a new model of half cross section of railroad bed,formulas of sectional area calculation and earth-rock volume integral are derived in this paper. This method can meet different degrees of accuracy ,and it can be used not only in rough count by manual, but also in computer-aided railway location work.
