摘要: 与测量机器人相比,GPS技术具有全天候作业、可提供三维信息、受天气影响小、观测效率高等优点,但应用于变形监测控制网时其观测精度能否满足要求一直是关注的重点。作者将GPS技术与测量机器人同时应用于白莲河抽水蓄能电站变形监测控制网观测,并从观测边长、点位精度和点位较差分析等方面对GPS技术和测量机器人的观测成果进行了对比分析,结果表明两者观测成果一致性很好,说明GPS观测能够满足二等变形监测网的精度要求,可在实际工程中推广应用。

Abstract: The authors observed the deformation monitoring network for Bailianhe pumped storage station through  georobot and GPS technology. The control network was firstly observed by georobot with onboard deformation monitoring automatic observation system. The observation efficiency and the quality of results were reduced by atmospheric temperature distribution. Furthermore, GPS technology, for its all-weather operation, uniform 3-D information, and high efficiency, was employed to observe the deformation monitoring control network. Through comparison in terms of observation side length, point error and position difference, we found that the observation results by GPS technology and georobot were consistent. The measurement of GPS technology meets the accuracy requirement of second-order deformation monitoring control network and has good practical application prospects.

Key words:  GPS, georobot, deformation monitoring, control network
