全站仪三角高程代替四等水准在水利水电工程中的应用

在水利水电工程测量中，很多时候需要使用三角高程测距代替水准测量。本文从三角高程基本原理和误差来源出发，讨论了三角高程测量应进行的误差改正和注意事项，论述了全站仪三角高程测量在水利水电测量工程中代替四等水准的可靠性。

The Application of Total Station Triangle Elevation Replaces the Fourth Level in Water Resources and Hydropower Engineering

In the water conservancy and hydropower engine-eering survey, most of the time people need to use trigo-nometric elevation range instead of leveling. This article embarks from the basic principle of triangular elevation and error sources and discusses the trigonometric leveling error correction and announcements, and discusses the reliability of triangle elevation surveying instead of the fourth level in the water resources and hydroelectric power measurement project.
