摘　　要：根据全站仪的特点,提出了储罐基础沉降、径向变形和罐体倾斜在线测量技术,并分析了不同标准规范对储罐失稳变形评估的指标要求。对某油库外浮顶原油储罐进行了在线测量和数据分析,对比规范得到了在役储罐的整体失稳与变形状况。理论和实践表明,全站仪在储罐区应用时,能够满足日常失稳及变形监测的精度要求。According to the characteristics of tacheom- etry, the online measuring technology of storage tank foundation settlement, radial deformation and tank body tilting is proposed. Additionally, the requirements of different specifications for assessment of in- stability and deformation of storage tank are analyzed. The overall instability and deformation of in - service storage tank is obtained through online measurement and data analysis of crude oil storage tank on the cov- ered floating roof of certain oil depot. According to the theory and practice, it indicates that the require- ments for the precision in daily monitoring instability and deformation could be satisfied when the taeheom- etry is applied in the storage tank area.
