摘　　要：结合三家子跨丹大高速特大桥平面控制网的布设情况,以边长为观测值,待定点坐标为未知参数,在三角网中采用GPS测量定位后,利用Poweradj4.0软件对GPS独立基线向量网进行平差,并得出测边网高精度平差理论,应用于轨道铺设、轨道精调和后期运营维护的永久性控制基桩。This paper is routed combining three sub-high-speed cross-Dan Bridge Horizontal Control Network to side length observations pending point coordinates of the unknown parameters,after triangulation employed using GPS positioning measurements using Poweradj4.0 independent software for GPS baseline vector network for adjustment,measure and draw the side-netting precision adjustment theory,and for laying the track,the track tuning and post-operation control group maintained permanent pile.
