Abstract
EH4 high frequency magnetotelluric method is used to detect the depth of bedrock and groundwater table,which provides a theoretical basis for regional groundwater environment investigation.EH4 high-frequency magnetotelluric data are inversed by two-dimensional inversion to determine the low-resistance anomaly area and explain it quantitatively.According to the geophysical test section,the bedrock interface is determined,and the groundwater depth is deeper than 70m.The results show that EH4 high frequency magnetotelluric method can effectively detect the depth of groundwater,combined with hydrogeology,borehole data can greatly improve the interpretation accuracy.关键词
