基于公路单曲线三维坐标计算编程模型

The Programming Model of Three-dimensional Coordinate Computation Based on Common Curve of Road

可编程序计算器在公路放样坐标计算没有真正实现数据资源共享和有效连接。本文建立三维坐标计算模型,并对计算进行一一剖析,同时给出其通用的计算公式,为优化组合创造了条件,也为二维计算转三维计算打下了基础。一段曲线起算数据仅一次键入,计算的任意性和无限循环性,使野外放样人员作业效率大大提升,实践表明,该方法是可行的,计算模型是可靠的。

When we use programme preface calculator executing the calculation of setting-out coordi nate of road, the data of original importation and temporary calculation, which is not real shared and linked effectively. Building up the model of three-dimensional coordinate computation, and carrying on the detailed analysis to the calculation,give its general calculation formula at the same time , to create the condition for the excellent turned combination, also building up the foundation for two-dimension to three-dimension. Only one key-in on the first data for a curve, calculating arbitrarily and circulating application,it makes surveyor＇s work more efficiency. It is verified that, this kind of method and the computation model is feasible.
