摘要： 随着测量机器人精度的提高,精密三角高程测量在跨河水准测量中得到了广泛的应用。根据精密三角高程测量的严密计算公式,通过误差传播定律推导了测量结果的误差公式,证明控制仪器的垂直角和测量距离,能够提高测量精度,达到二等水准测量精度。通过在大藤峡水利枢纽工程左右岸高程联测中的应用,证明该方法能够达到二等水准测量精度要求,且可提高工作效率。应用成果对类似跨河水准测量具有一定的借鉴意义。

Abstract: With the improvement of the precision of measuring robot, the precise trigonometric elevation measurement has been widely used in river-cross leveling. Based on the exact formula of precise trigonometric height measurement and the error propagation law, the formula of measurement error is derived in this paper. Controlling the height angle and measuring distance of instrument could improve the measuring accuracy and reach the second-class leveling accuracy. The present method was applied to the left and right bank elevation survey of Datengxia hydro-junction project, and results demonstrate that the method meets the requirements of second-class leveling accuracy and enhances working efficiency. The application results can be used for reference in similar river-cross leveling.

Key words: precise trigonometric leveling, river-cross leveling, second-class levelling, error propagation law, Datengxia hydro-junction project
