元谋苴林地电场改造前后数据分析

Data analysis before and after the transformation of Yuanmou Julin electric field

  • 摘要: 以楚雄地震监测中心站元谋苴林地电场观测资料为研究对象,结合该地电场观测以来两次改造的思路与具体内容,对两次改造前后共三个时间段内的观测数据曲线变化特征及数据质量进行对比分析,得到以下经验,供其他地电场观测的台站进行改造与建设作参考:1.固体不极化电极的抗干扰能力及稳定性远超铅电极;2.电极埋深需更多考虑土壤电性一致而非注重埋设深度,应在建台时做好场地的地勘工作,确保各电极埋设后接地电阻无较大差距,同时还应注意电极引线埋深一定要大于农户日常耕作可能触及的深度;3.双“L”型布极需严格按照地电台站建设规范布设长短极距;4.对于架空线路绝缘问题,可做抱箍与电杆间先通过绝缘橡胶垫绝缘,再做抱箍与钢绞线间通过绝缘子再次绝缘,特别是有地电阻率同场地观测台站,更应注重钢绞线绝缘问题。

     

    Abstract: Taking the electric field observation data of Yuanmou Julin of Chuxiong Earthquake Monitoring Center Station as the research object, combined with the ideas and specific contents of the two transformations since the geoelectric field observation, the observation data curve variation characteristics and data quality in three time periods before and after the two transformations are compared and analyzed, and the following experience is obtained, which can be used as a reference for the transformation and construction of other geoelectric field observation stations : 1.the anti-interference ability and stability of solid non-polarized electrodes far exceed lead electrodes ; 2.Electrode buried depth need to consider more consistent soil electrical properties rather than pay attention to the buried depth, should do a good job in the construction of the site geological prospecting work, to ensure that the electrode buried after the grounding resistance without a big gap, but also should pay attention to the electrode lead buried depth must be greater than the farmers daily farming may touch the depth ; 3.Double 'L ' type pole arrangement needs to be strictly in accordance with the construction specifications of the geoelectric station to arrange the long and short pole spacing ; 4.For the insulation problem of overhead lines, it can be done between the hoop and the pole first through the insulation rubber pad insulation, and then between the hoop and the steel strand through the insulator re-insulating, especially the ground resistivity with the site observation station, more attention should be paid to the insulation of the steel strand.
