【摘要】 随着国民经济的快速发展,地电阻率的观测环境受到各种干扰,其中采用直流牵引技术的城市轨道交通干扰尤为严重,致使一些地电阻率观测台站的观测数据无法满足规范要求,部分台站因此被迫搬迁。进一步改善观测系统测量模式,提高其观测精度势在必行。通过多种方法实验,提出了一些抗干扰措施,达到了提高观测精度的目的,为进一步提升地电阻率观测质量做了技术铺垫。更多还原

【Abstract】 The rapid development of the national economy,earth resistivity observation environment is interfered. City rail traffic interference which adopts DC traction technology is particularly serious. Some data of earth resistivity observation stations can’t meet the standard requirements,and some stations were forced relocation. Through the test and analysis of the stations with serious interference,the paper puts forward some anti-interference measures,and makes a technical basis for the further improvement of the quality of the earth resistivity observation.更多还原
