探究内蒙古乌加河地电场台电极布设深度增加对数据质量的影响

Exploring the influence on data quality of the burial depth of electrodes in the Wujiahe geoelectric field Abservatory Station,Inner Mongolia Province

  • 摘要: 本文旨在通过对比分析,探讨乌加河台在2018年11月将LGB-3固体不极化电极的埋深从原有的3.5米增加至5米后,观测数据质量的变化情况。为达此目的选取了2015年至2023年的相关数据进行计算并分析。研究结果表明:1. 布设深度加深后,相关系数未见显著变化,各测向之间的相关性与电极的埋深不存在正负关联。2. 日差值计算的结果显示,数据的稳定性得到了进一步的提升,观测数据的质量得到提升。3.日均值动态曲线分析,4月-9月降雨频发的期间,各测向的受干扰的次数及幅度明显减小,显示出更强的抗干扰能力。

     

    Abstract: This article aims to explore the changes in observation data quality at the Wujiahe Station after increasing the burial depth of the LGB-3 solid non-polarized electrode from the original 3.5 meters to 5 meters in November 2018 through comparative analysis. To achieve this goal, relevant data from 2015 to 2023 were selected for calculation and analysis. The research results indicate that: 1. After deepening the deployment depth, there was no significant change in the correlation coefficient, and there was no positive or negative correlation between the correlation between each lateral direction and the burial depth of the electrode. 2. The results of the daily difference calculation show that the stability of the data has been further improved, and the quality of the observed data has been enhanced. 3. Daily average dynamic curve analysis shows that during frequent irrigation and rainfall from April to August, the number and amplitude of disturbances on each side are significantly reduced, demonstrating stronger anti-interference ability. 4. After analyzing the dominant azimuth angle of the earth's electric field, it was found that there was no significant change in the amplitude of alpha deflection and variation, indicating that the dominant azimuth angle was not affected by the deepening of electrode layout.
