摘　　要：为了解决黄河下游河道淤积测量作业过程中存在的树木、建筑物遮挡仪器设备、烂泥滩、较危险的几乎垂直的陡崖测量困难等问题,提高测验效率以及数据的精度和可靠性,本文采用GNSS RTK倾斜测量技术,选用徕卡GNSS设备GS18I的倾斜测量功能分别对硬化路面、水边、老滩沿、树林、断面控制点等比较困难的测量环境进行可靠性和精度测试,测试结果表明:不同测量场景下倾斜约30°、45°、60°、90°,所得结果与无倾斜状态下的数据的坐标差值在7 cm以内,满足河道测验的技术要求。在2023年黄河山东段河道断面老滩沿、烂泥滩、树木茂密地带等困难区域地形点测验中,应用倾斜测量技术获取的成果与垂直状态下的测量成果进行对比,坐标差值在5 cm以内,精度符合规范要求,提高了作业效率,降低了劳动强度,可广泛应用于河道测验、铁路测量、电力测量等领域中。In order to solve the problems of difficult measurement in the process of measuring sedimentation in the lower reaches of the Yellow River,such as trees,buildings obstructing instrument equipment,muddy beaches,and dangerous almost vertical cliffs,and to improve testing efficiency and data accuracy and reliability,this paper adopts GNSS RTK tilt measurement technology,and uses the tilt measurement function of Leica GNSS equipment GS18I to test the reliability and accuracy of difficult measurement environments such as hardened road surfaces,water edges,old beach edges,forests,and section control points.The test results show that under different measurement scenarios,the tilt is about 30°,45°,60°,and 90°.The coordinate difference between the obtained results and the data without tilt is within 7cm,which meets the technical requirements of river testing.In the 2023 topographic point test of difficult areas such as the old beach,muddy beach,and densely forested areas in the eastern section of the Yellow River,the results obtained by using tilt measurement technology were compared with the measurement results in the vertical state.The coordinate difference was within 5cm,and the accuracy met the standard requirements,improving work efficiency and reducing labor intensity.It can be widely used in fields such as river testing,railway measurement,and power measurement.
