摘要
对霍拉山洞体数字化形变观测资料干扰进行分析,结果表明:1伸缩仪对气象因素干扰响应灵敏,可以通过一些密封措施减少洞体内气流扰动对观测资料的影响;2人为干扰不可避免,可以采取有效措施减少干扰影响;3供电系统干扰产生无效数据,间接影响资料连续率,实时监控手段能够及时掌握供电情况;4数采原因造成的缺记呈一定规律性;5观测资料异常时,认真按照流程进行异常核实。
In this paper, the disturbance of digital deformation observation data of Huola cave is analyzed and discussed. The results showed that: (1) The extensometer is most sensitive to meteorological factors interference response,by some measures, the sealing body piercing airfl ow in disturbance impact on observation data can be reduced;(2) Human interference is inevitable, it can take effective measures to reduce the disturbance effect;(3)Power supply system interference to indirectly influence the data rate of continuous,real-time monitoring method can timely grasp the power supply;(4) Lack of record caused by the data collector presents the regularity;(5) for abnormal observations,careful verifi cation according to the abnormal process is necessary.
