| 摘 要： | 传统上道路工程勘测、设计、施工各单位统一采用以初测导线点处垂线为基准线、水准面为基准面的,把各相邻测站处局部水准面相连拼接成一个统一带状的平面坐标系统（定义为道路工程渐变平面坐标系）。本文提出顾及地球重力场模型,用GPS直接建立垂线和水准面系统的道路工程渐变平面坐标系的解决方案,从理论上统一了勘测坐标系（GPS平面坐标系）和设计、施工坐标系（道路工程渐变平面坐标系）,消除了其间存在的系统误差。

| Abstract: | Gradual Plane Coordinate System for Road Engineering(GPCSRE) as a definition,in which the vertical line is regarded as datum line and the level surface is regarded as datum plane at preliminary survey traverse point,is spliced by individual adjacent local level surface and becomes a united banded plane coordinate system.Traditionally,GPCSRE is applied by reconnaissance,design and construction organization in road engineering simultaneously.This paper presents a solution to build GPCSRE,which belongs to the ... |
