一种基于三角高程测量的高程控制网建立方法

A method of Establishment for Vertical Control Network Based on Trigonometric Leveling Method

分析了传统三角高程测量与一种新的三角高程测量方法的误差来源,并尝试计算了两者能达到的精度水平。结合工程实践,分析了使用新型三角高程测量方法代替水准测量的适用性、可行性、数据处理方法、可达到的精度水平,得出了这种新型三角高程测量方法可达到四等水准测量精度水平的结论,但受工作条件限制,仅宜作为四等水准测量的补充与替代方法。

This paper analyzed the source of error of traditional trigonometric leveling method and a new kind of trigonometric leveling method. Combined with project,the applicability,feasibility,data process method and precision were analyzed. The conclusion is the precision of new trigonometric leveling method can achieved the forth order leveling. But because of its boundedness,it should be used as the replacement of the forth order leveling.
