三角高程在跨河水准测量中的分析与应用

Analysis and Application of Triangle Evaluation in River-crossing Leveling

分析了三角高程测量的数学原理及各种影响测量精度的误差来源,指出三角高程测量代替长距离的跨河水准精度的可靠性及实践的可操作性。并通过工程实践证明,在一定的观测条件下,其精度可以达到二等水准的精度要求。

This paper analyzes the mathematics principles of triangle evaluation and various error sources affecting its accuracy. Through pointing out the reliability and practice feasibility of replacing long distance river-crossing leveling precision with triangle evaluation and the engineering practice, it indicates that under certain observing conditions, the precision can reach the second-grade accuracy standard.
