摘　　要：针对布设的城市地铁GPS复测控制网,提出了地铁控制网复测的必要性。并在复测网形优化分析的基础上,讨论了起算点与地铁控制网不兼容性对精度的影响和筛选方法,实例表明此方法的有效性。In view of disposing GPS re-measurement control-network of the cities subway, the authors raised the re-measurement's necessary of subway control-network. Based on optimization analysis of re-measurement control-network, we still discussed the selected initial points un-compatibility about matching GPS network as well as its influence to precision. The practice shows that this method is effective.
