摘　　要：在进行大型水利工程全球导航卫星系统(GNSS)控制网数据处理过程中,为了满足边长投影变形的精度要求,需要改变高斯投影中央子午线和选择合适高程抵偿面。针对抽水蓄能电站工程控制网的布设、观测和数据处理等具体问题,本文对逢石河工程控制网的观测和数据处理等方面进行了全过程论述,阐述了抽水蓄能电站工程控制网的作业流程、建立方法、关键技术和成果精度,建立了抵偿投影面的任意带高斯投影工程坐标系统,并获得了精度可靠的坐标成果,对类似项目的生产具有借鉴意义。In the data processing of establishing a GNSS control network for large-scale hydraulic engi‐neering,methods involving the adjustment of the central meridian in Gauss projection and the selection of an appropriate elevation compensation surface are used to meet the accuracy requirements for the side length projection deformation.In order to address the specific issues related to the layout,observa‐tion,and data processing of the pumped storage power station control network,this paper comprehen‐sively discusses its entire process,focusing on the observation and data processing of the Fengshi River project control network.It establishes an arbitrary zone Gauss projection engineering coordinate system with a compensating projection surface and obtains coordinate results with reliable accuracy.The tech‐nical procedures,methods,key technologies,and products accuracy of the pumped storage power sta‐tion control network are illustrated.It can provide useful reference and promote in similar projects.
