云南省罗茨地电场的干扰排查及数据变化特征分析

Interference and changes in data characteristics of Luoci geoelectric observatory station in Yunnan Province

  • 摘要: 本文以罗茨地电场观测资料为研究对象,利用该地电场观测数据对其主要干扰源进行定位及分析,发现其主要干扰源为电极引线破损、测区温泉经营户抽水机漏电、大型基建施工及降雨所致,分别介绍此4类主要干扰源的排查过程及其典型变化形态,为解决干扰问题提出一些思路;利用相关性分析、差分等手段对该地电场观测数据质量进行评价,并归纳总结在实际工作中提升观测数据质量的方法;在同一个地电暴事件中,通过与周边的元谋苴林地电场做观测数据的对比,总结罗茨地电场数据在地电暴事件中的变化特点,并分析两个地电场观测记录不同的原因。该论文能为台站工作人员对该地电场观测资料的认识和把握提供较好的参考,并为噪声识别和震情分析提供指导,以及对后期该地电场的改造提供科学依据。

     

    Abstract: The observation data from the Luoci geoelectric observatory station were studied. The main sources of data interference were identified and analyzed using the observation data from a geoelectric observatory station. The main sources of data interference were electrode lead damage, water pump leakage in the hot spring operators, large-scale infrastructure construction, and rainfall. The typical changes in these four main interference sources were investigated, and solutions were proposed to reduce data interference. The quality of the geoelectric observatory station observations was evaluated using correlation analysis and differences between observations. Methods of increasing observation quality work are summarized. The characteristics of the Luoci geoelectric observatory station data were compared with those obtained at the nearby Yuanmou Julin geoelectric observatory station to determine their differences. The reasons for the differences between the two geoelectric observatory station observation records were identified. This study provides a reference for helping station staff understand geoelectric observatory station observation data, identifying data noise, and analyzing seismic data. A scientific basis is provided for upgrading geoelectric observatory stations.
