红崖头水位干扰分析及解决途径

Analysis oninterference factors of water level in Hongyatou well and its solution

梳理各种干扰对仪器的影响,有助于更好地识别前兆异常,消除干扰可以提高数据观测质量。本文从观测系统、自然环境、人为干扰等方面对榆社红崖头观测站水位典型干扰进行归类分析,并给出相应的解决途径。分析结果表明,红崖头井水位受到的观测系统干扰主要为供电故障、电源电压不稳、泄流系统干扰;自然环境干扰主要为强对流天气;人为干扰主要包括探头位置改变、取水样等。

Sorting out the influence of various interferences on instruments is helpful to better identify precursor anomalies,and eliminating interference can improve the quality of data observation.This paper classifies and analyzes the typical interference factors of the water level at Hongyatou Observation Station in Yushe from the aspects of the observation system,natural environment and human interference and gives the corresponding solution.The results show that the observation system interferences mainly include the failure of power supply,unstable power voltage and blockage of flow discharge system.The natural environment interferences mainly include severe convective weather.The human interferences mainly include the change of probe position and water sampling.
