测距三角高程法跨河水准测量是跨河水准测量几种方法中比较重要的一种方法。其特点是适合长距离的跨河水准,不受两岸高差限制,观测精度高。缺点是前期准备工作烦琐,观测程序复杂,计算过程复杂。作为一种高等级常规跨河水准测量方法,其测量误差也不容忽视。笔者结合自身的测量经验,探讨了测量中的误差来源及消除措施等。

Trigonometric cross-river leveling is one of the important methods of cross-river leveling.It works well in long distance cross-river leveling with high observation accuracy not limited by the elevation difference between the two sides of the river.However,it has the drawback of complex preparation work,observation process and calculation process.As a high-order cross river leveling method,its measurement error cannot be ignored.Based on the surveying practice of the author,this paper studies the source of the measurement error and the ways to eliminate it.
