大型抽水蓄能电站施工控制网复测与精度分析

Measurement and Accuracy Analysis of Construction Control Network for Large Pumped Storage Power Station

施工控制网是抽水蓄能电站土建施工和机电安装的重要基准,惠州抽水蓄能电站施工周期长(历时7a)必须定期复测、检验其稳定性,为施工提供稳定的测量精度。论文结合惠州抽水蓄能电站施工控制网复测实例,采用科学的方法进行复测,得出的结果与原成果进行的比较和分析,成果正确、稳定、可靠,为电站安全施工提供了高精度测量基准。

The construction of the control network is an important benchmark of Pumped Storage Power Station civil construction,electrical and mechanical installation,Huizhou Pumped Storage Power Station construction period（which lasted seven years） must be regularly re-testing,to test its stability for the construction to provide a stable measurement accuracy.In this paper,the construction of Huizhou Pumped Storage Power control Network retest instance,using scientific methods,retest,the results of the original results of the comparison and analysis,the outcome is correct,stable,reliable,and provides highly accurate measurement of the power station construction safetybenchmarks.
