| Abstract: | The new arrangement of buried electrode resistivity is put forward to the relocation of Jiangning site. This scheme adopts shortening the current distance and using deeply buried electrode to suppress the interference from subway and green house. We introduce the field layout, measuring items design, the installation technology specification and the construction essentials of Jiangning Deep Borehole Geoelectric Station. The problems existing in the construction are discussed. By analyzing the resistivity data from 2015 to 2016. The result shows that application of the geo-electrical observation system in deep borehole can improve the signal-to-noise ratio and ease the confliction between the land of geo electrical observation and the economic construction. The geo-electrical resistivity observation in deep borehole is new promising way. |
