道路设计中线一体化测设方法研究及程序设计

A research on the integrated layout method and the program design of road design central line

介绍了一种道路设计中线一体化测设的数学模型和方法 ,根据各桩点里程及其离开中线的距离 ,利用开发出的中线和边桩等点放样程序 ,解算出该点的理论设计坐标 ,然后由附近的高级控制点用极坐标法测设。运用于桂林市中山路扩建工程中的中桩测设 ,表明该方法及程序高效、灵活、功能大 ,特别是在地形既复杂又在曲线上的中桩、边桩的放样中 ,显示出更强的优越性。

This paper introduces the integrated mathematical model and layout method.Based on design middle line of a road according to mileage of every hub and its distance from the central line,theoretically designed cordinates of the hubs can be worked out by the practical layout program developed for central line and stele hubs.Then the hubs can be laid out from the high-order control point nearby.These method and program were put into practice during the reform of Zhongshan Road in Guilin. The practice proved that the integrated method and program are more efficient, more adaptable and more available and their advantages proved superior to the layout of central line and side hubs on curves in rough terrains.
