| 摘 要： | 对集宁2017年4月1日-5月31日地电阻率原始观测数据曲线常规分析发现，NS、EW测道数值差异明显，采用电测深曲线进行对比分析，发现2测道电阻率数值基本一致。在同场范围内，地电阻率与电测深曲线应同步变化。对集宁地电阻率布极区、观测环境、观测系统、装置系统进行系列检查、测试，发现NS测道导线线芯与导线铠导通，导线铠与避雷箱箱体接触导致线路漏电，造成数值出现误差。通过对外线路以及电极引线等进行优化改造，集宁地电阻率观测数据恢复正常。

| Abstract: | The conventional analysis of the original observation data curve of ground resistivity from April 1, to May 31, 2017 found that the values of NS and EW were significantly different, and the comparison analysis was conducted by using the electric sounding curve. It was found that the values of the resistivity of the two measured channels were basically consistent. A series of checks and tests were carried out on the resistivity field, observation environment, observation system and device system in Jining, and it was found that the wire core and armor of NS component wire was short out and wire armor connects with lightning protection box, which led to leakage of power, resulting in numerical error. The observation system was optimized and improved, and then the resistivity observation data in Jining area was restored to normal. |
