| 摘 要： | 本文运用精密三角高程测量技术作为跨河高程传递的方法,探讨其中的关键技术问题。在水面视距分别为1.85km和2.2km并且不借助特制觇牌直接观测棱镜的情况下,通过优化观测图形以缩短两岸对向观测的时间差,利用一台全站仪,精确测量出云龙湖两岸的高差,精度可达二等水准要求。最后总结其中多次实验的经验以及教训,以期为同行提供借鉴。

| Abstract: | On the basis of the theory of precise trigonometric leveling,some key issues were discussed on river-crossing leveling in the paper.With optimal observation process,the altitude difference was measured precisely in the distance of 1.85km and 2.2km across Yunlong Lake using only one total station and corresponding prisms,which could meet the standard completely.Finally,some experience and lessons were summarized for reference. |
