【WGMD-4 】Application of geophysical methods in the investigation of organic contaminated sites
Ⅰ.Introduction The survey site was a decommissioned chemical plant in Nantong, Jiangsu Province, with a survey area of 120,000 square meters. Traditional drilling and sampling engineering has a large amount of work and a long cycle. Using high-density resistivity method…
【WGMD-4】Application of geological disaster landslide investigation
Ⅰ.Introduction Geophysical exploration using two Dimensional (2D) electrical resistivity tomography (ERT) survey plays a significant role in determining the subsurface resistivity distribution by making measurements on the ground surface. From these measurements, apparent resistivities are recorded during the fieldwork, which…
Application of High-density Electrical Method in Underground Cavity Detection
【WGMD-4 High-density Electrical Method System】Application of High-density Electrical Method in Underground Cavity Detection Abstract In the old house renovation construction project in Jinan City, Shandong Province, the high-density electrical method was used to detect underground cavities on the foundation of…
【WGMD-4】Application of Electrical Resistivity Tomography (ERT) Method in Borehole Tests in Tajikistan
Ⅰ.Introduction The local climate in Tajikistan is highly variable, and soil salinization and alkalization are extremely severe. This has led to scarce natural vegetation along the entire river. The situation also contributes to river dam problems and serious soil erosion.…
【WGMD-4】Application of electromagnetic equipment in the search for gold
Ⅰ.Introduction The WGMD-4 centralized high-density electrical method system have the ability to resist resistivity imaging and store data so that the approximate location of the gold mine and data analysis can be determined. Ⅱ.Survey method The contrast between the physical…
