| Abstract: | The principles and methods of precise trigonometric leveling technology are introduced. Then effects of high altitude mountain atmospheric refraction on trigonometric leveling are analyzed and corresponding solutions are proposed to combine with the actual situation of high altitude mountain. The best practice sessions are developed based on job experience in high altitude mountain. The effects of temperature and pressure on trigonometric leveling are analyzed and elaborated from the quantitative by being combined with parameters of measuring instrument and related mathematical models. The feasibility of the application of precise trigonometric leveling substitute sec- ond leveling is validated by engineering data. |
