摘　　要：由于大秦铁路横穿测区,夏季降雨时电极与铁轨形成通路,对地电阻率观测造成较大影响,使观测精度下降。ZD8M观测系统远离铁路并深埋电极后,可以减小地表降雨及地下水位对地电阻率观测数据的影响,使观测精度提高。河北阳原地震台地电阻率观测系统较好,数据可靠、稳定、连续,观测时间较长,对晋冀蒙交界地区的成组地震有较好响应,对晋冀蒙及首都圈地区地震监测、预报、地震科学研究中具有重要意义。Since Datong-Qinhuangdao railway passes through the survey area of Yuanyang Seismic Station,and the rail and electrode consist of electric path during summer rainfall, the ground resistivityobservation accuracy in the station is greatly impacted on. After the ZD8M observation systemis reconstructed by moving far away from the railway and increasing the depth of the electrode,which can reduce the influence of surface rainfall and underground water level on the earthresistivity observation data and improve the accuracy of the observation, the resistivity observationsystem in Yangyuan station, Hebei Province is in good status, with reliable data and long timestable continuous observation. It has a good response to the grouped earthquakes in the junction ofShanxi, Hebei and Inner Mongolia areas and is of great significance to the earthquake monitoring,prediction and scientific research of Jin-Ji-Meng and capital circle area.
