摘要
本文针对布测隧道GPS网的坐标转换与高程改化问题进行了讨论,并提出了解决途径和实施方法,通过军都山隧道工程作了验证。
Aim at the problems of coordinate transformation and elevation change in the setting up of tunnel GPS net. in this paper a discussion is made, and the ways of solving and the method of practicing of these problems are presented. It is verified by the case history of Jundushan tunnel project surveying.
