摘要
针对水电行业边坡变形监测中山高坡陡、卫星信号遮挡严重,以及GPS网型设计受到限制,网中相邻监测点距离只有几百米,很难满足《全球定位系统(GPS)测量规范》中D级网的边长要求的情况,结合工程实例,对GPS短边网的数据处理和精度进行分析。使用全站仪EDM检核验证GPS短边测量距离满足测距精度要求,发现边长误差在5 mm以内,并对GPS网的检核进行探讨。希望在变形监测工作中起到参考价值。
Against deformation monitoring for the hydropower industry, high mountains and steep slopes, as well as GPS satellite signal blocking and GPS network design restricted, network monitoring points adjacent distance of only a few hundred meters, it is difficult to meet the 《global positioning system （GPS） measurement specifica- tions》grade D side network requirements of the situation. With engineering examples, the short side of the GPS network data processing and precision analysis using GPS Total Station EDM verification checklist to meet the short side measuring distances ranging accuracy requirements are presented. The side length error less than 5 mm, and seized GPS network nuclear discussed are found. The deformation monitoring reference value shoold be hope to Dlav.
