| 摘 要： | 为拓宽某段公路,在公路两旁布设E级GPS控制网,采用北极星9600型接收机进行观测,应用南方测绘基线后处理软件进行三维无约束平差,直接应用国家高斯平面投影,长度综合变形超过工程测量规范(2.5 cm·km-1)的要求,因此必须选择适当的投影带重新进行高斯投影,最终得到的每公里长度变形满足规范要求,体现了合理选择坐标系在...

| Abstract: | In order to widen the road,setting up E-level GPS network along the road,observation by using Polaris 9600 GPS receivers,at the end of outside observation,three-dimensional adjustment no constraints by application the after processing software baseline of south survey,direct application state gauss plane projection,length measuring standard comprehensive deformation over engineering（2.5 cm·km-1） requirements,so must choose appropriate projection belt to re-run gaussian projection,finally obtained the length deformation per kilometer meet the standard request,has manifested the reasonable choice of coordinate system in highway rebuilding project of importance. |
