摘　　要：针对地震前兆观测中的地电阻率法,研制出适合其观测系统的检测装置,并对装置进行理论仿真与实地检测。首先,通过对地电阻率测量系统进行剖析,指出现有检测系统的不足;然后,根据观测系统需求进行分析,设计对应的检测指标和电路,并将仪器检测精度设计至0.001级别,提升设备性能;最后,借助Simulink工具对检测装置进行理论仿真,对比研究干扰对观测结果的影响,并随机选取甘肃地区地震观测台站进行实地检测。结果表明,检测装置不仅能直观展示地电地阻率测量系统的工作状态,而且能精准评价地电阻率观测系统的实时优劣性,填补地电阻率观测系统检测装置的空白,为地震一线工作人员提供极大便利。We focus on the apparent resistivity method in earthquake precursor observation,develop a detection device suitable for its observation system,and conduct theoretical simulation and on-site testing on the device.First,we analyze the apparent resistivity measurement system,and point out the shortcomings of existing detection systems.Second,according to the demand analysis of observation system,the corresponding detection index and circuit are designed,and the detection accuracy of instrument is designed to 0.001 level to improve the performance.Finally,the developed device is theoretically simulated using Simulink,and the impact of interference on observation results is compared and studied.Random earthquake observation stations in Gansu region are selected for on-site testing.The results show that the developed device can not only visually display the working status of apparent resistivity measurement system,but also accurately evaluate the real-time superiority and inferiority of apparent resistivity observation system,and fill the gap in detection device of apparent resistivity observation system and provide great convenience for frontline earthquake workers.
