Abstract: Because of non-uniform distribution of atmospheric density, atmospheric refraction has great influence on the monitoring result of Total Station. As most deformation monitoring by Total Station is one-way observation, meteorological correction should be carried out. The correction includes meteorological factor correction and practical correction. The paper mainly introduces the practical correction, for reference.

Key words: Total Station, meteorological correction

摘要: 由于大气密度的分布极不均匀,大气折光对全站仪的测量结果影响较大,又鉴于全站仪进行大坝变形监测多数采用的是单边观测,因此,需对观测结果进行气象改正。气象改正有气象元素改正法和实用改正法两大类,这里主要介绍实用改正法。
