摘要
在精密三角高程测量的原理、误差来源及误差分析的基础上,对光电三角高程测量及二等水准测量的精度进行估算,探讨了精密三角高程测量在特定条件下代替二等水准测量的关键问题及可性行,提出了采用徕佧TCA2003全站仪具体操作方法及要求,并在向莆铁路控制点的水准联测中进行了验证,取得了较好的经济效益。
Based on the precise trigonometric leveling principle, error sources and error analysis, the preci- sion of photoelectric triangulated height and second-grade leveling survey is evaluated and the feasibility of the precise trigonometric leveling to replace the second-grade leveling is studied. In this paper, the specific opera- tion method of The TCA2003 total station is put forward and is verified in the Xing-Pu railway leveling process.
