摘　　要：介绍了青岛海湾大桥GPS首级平面控制网的布设方案、观测方法及数据精细处理方法,从每个环节进行控制,以保证达到设计精度。最终三维无约束平差结果优于5.0mm,二维平差最弱点点位精度也达到了4.2mm,实际高精度的结果证明该方案可保证首级控制网满足设计及相应的规范要求,大大超过了预计的精度,给同类工程带来较大的借鉴价值。Introduces the allocating plan, observation technology and the fine processing method of data forprimary level control network of Qingdao Bay Major Bridge. GPS technology is used in this project. Eachprocedure is strictly controlled. Finally, design of the network is verified by the high precise result. Its ac-curacy is superior to 5.0mm in 3D, 4.2mm in 2D. And it could give reference to similar project.
