一种利用精密全站仪实施跨江水准测量的方法

A Method of Leveling Across River by Using Precision Electronic Total Station

在跨江水准测量原理基础上,提出一种利用精密全站仪实施大跨距跨江水准测量的方法,并结合长江隧道工程介绍了具体的作业方法和量测结果。通过实际量测结果分析证明,该方法可以消除球气差影响。

This paper puts forward a method of large span leveling across river by using precision electronic total station base on theory of leveling across river, and introduces material practices and measurement results in engineering of Changjiang River Tunnel. It has been proved by analysing measurement results that the method can eliminate the effects of Spheric and Atmospheric Aberrations, finally the author summarizes some considerations by using this method.
