五指山形变台定点形变观测资料内在精度分析

Internal accuracy analysis of fixed-point deformation observation data of Wuzhishan deformation station

  • 摘要: 本文对2016年1月—2021年12月连续6年五指山形变台定点形变观测资料内在精度进行统计分析,台站水管倾斜仪和铟瓦棒伸缩仪内在精度质量较好;宽频带倾斜仪两个分量内在精度年均达到优秀指标的概率仅50%,且自2020年1月出现观测数据内在精度质量持续下降,导致观测资料质量不高。提高数据内在高质量的重要条件是确保观测数据的连续率,因此,提升台站人员业务水平和保证必要的备机备件是当务之急。

     

    Abstract: This paper presents a statistical analysis of the internal accuracy of the fixed-point deformation observation data of Wuzhishan deformation station from January 2016 to December 2021. The internal accuracy of the station’s water pipe tiltmeter and indium tile rod extensometer is good. The probability that the internal accuracy of the two components of the broadband tiltmeter reaches the excellent index is only 50%. Since January 2020, the internal accuracy quality of the observation data has been decreasing, resulting in the low quality of the observation data. The important condition for improving the internal accuracy quality of data is to ensure the continuous rate of observation data. Therefore, it is urgent to improve the operational level of station personnel and to ensure the necessary spare parts.
