公路施工测量中线细部点坐标计算程序设计

Center line detail point coordinates calculation program design in highway construction survey

本文把整段公路分解成直线、圆曲线、缓和曲线3种基本线型,再根据后两种曲线组合成各种平曲线的计算模块,这样整段公路又可以分为曲线和直线两类,最后根据一定的程序结构把曲线和直线计算模块组合成整段公路的计算程序。通过建立数学模型,进行程序设计,简化了各桩点的坐标计算。使道路中线放样工作变得方便、快捷、准确。

The whole highway is divided into three lines,（Liners,circular curves and easement curves）,and then,based on circular curve and easement curve,combined into calculation module of all kinds of flat curves,so that the whole highway can be divided into two kinds of curves and liners.According to the certain program structure,the curve and linear calculation module are combined into the whole highway calculation program.By establishing a mathematical model,the program design,and simplified the pile point coordinate calculation.Make road center line lofting work easy,quick and accurate.
