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。
由于大氣密度的分佈極不均勻,大氣摺光對全站儀的測量結果影響較大,又鑒于全站儀進行大壩變形鑑測多數採用的是單邊觀測,因此,需對觀測結果進行氣象改正。氣象改正有氣象元素改正法和實用改正法兩大類,這裏主要介紹實用改正法。

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 meteoro-logical factor correction and practical correction. The paper mainly introduces the practical correction, for reference.
