城市轨道交通施工期间GPS控制网检测与分析

Urban Track Transportation Construction Period GPS Control Net Examination and Analysis

针对城市轨道交通GPS施工控制网,在施工期间提出了控制网检测的必要性。在检测网设计优化、新旧控制网成果分析比较的基础上,讨论了GPS控制网作为地下导线起算点对指导贯通精度的重要性,实例表明检测方法的有效性,同时给出控制网检测合理建议,对其它类似工程具有参考价值。

Under the control of net being under construction specifically for city orbit traffic GPS , necessity having suggested that under the control of net checks in the period being under construction. On basis comparing in detecting net design optimization , new old under the control of net achievement analysis, the conducting wire having discussed that GPS under the control of net is ground starts counting from burning to the significance guiding to be versed in accuracy, the example indicates detecting method validity , give under the control of net detecting out the value suggesting that the similar project has a reference to other rationally at the same time.
