摘　　要：介绍了精密三角高程测量技术的原理和方法,分析了高海拔山区大气折光对三角高程测量的影响,并结合高海拔山区实际情况提出了相应的解决方案。根据在高海拔山区的作业经验制定了最佳作业时段,结合测量仪器参数和相关数学模型,从定量角度分析和阐述了温度气压对精密三角高程测量的影响,并提出了具体的解决方法,通过实践工程数据分析,验证了精密三角高程测量代替二等水准测量在高海拔山区应用的可行性。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.
