抽水蓄能电站GNSS施工控制网设计与建立

Design and Establishment of GNSS Construction Control Network for Pumped Storage Power Station

抽水蓄能电站通常选址在高山谷底、人烟稀少的地区。工程区常植被茂密,通行、通视困难,采用常规方法建立施工控制网工作量大、施测困难。文章以辽宁抽水蓄能电站施工控制网项目为依托,介绍了利用GNSS技术建立施工控制网的布置方案设计、建网实施、精度分析情况,分析了利用GNSS技术建立施工控制网的优势。对今后在抽水蓄能电站工程中建立GNSS施工控制网具有一定的借鉴意义。

Pumped storage power stations are usually located in mountain valleys and sparsely populated areas.The engineering area is usually covered with dense vegetation,thereby leading to difficult traffic and light of sight.Construction of construction control network with regular methods has shortcoming of large workload as well as difficult construction and measurement.Construction control network project of Liaoning Pumped Storage Power Station is regarded as support in the paper for introducing the layout plan design,network construction implementation and precision analysis of the construction control network established by GNSS technology,and the advantages of the construction control network established by GNSS technology are analyzed.It has certain reference significance for GNSS construction control network to be established in pumped storage power station project in the future.
