| 摘 要： | 当前线路平、纵、横设计要素面向的对象仍为为传统的施工测量手段，鉴于测量仪器及计算机的进步，设计要索的选择必须有利于快速、精确的获取施工放样数据。为建立统一数学模型，实现道路放样的数字化，避开了线路平面线形设计中常规组合方式，提出了曲线元的概念，统一概括为6种曲线元，通过坐标换算把曲线元上点位坐标统一到测量坐标系中。

| Abstract: | The object which the plane,the longitudinal section ,the cross section design face to is still- Traditional construction survey method at present. As a result of survey equipment and computer progress, the choice of the design factor must be advantageous to gaining precise construction lofting data fastly In order to realize the road location digitization this article avoids conventional combination way in plane geometric design aspect, puts forward the concept of cure unite in order to establish the unified mathematical model, the unification summary is six kind of cure unite. Transformate coordinates of road center-stake on cure unite to unification survey coordinate system through coordinate transformation. |
