基于导纳张量的航空大地电磁测量技术及应用
Airborne magnetotelluric measurement technology and application based on admittance tensor
摘要
Abstract
Airborne magnetotelluric method is an airborne frequency-domain electromagnetic method that measures the natural electromagnetic fields.It has the advantages of great detection depth,high measurement effi-ciency,minimal terrain influence,and being environmentally friendly.This paper briefly introduced the develop-ment history and measurement principles of airborne magnetotelluric method.Then introduced the basic concept of admittance tensor and the working methods of airborne magnetotelluric measurement using admittance tensor.Fi-nally,this method was applied to engineering surveys under complex terrain conditions.By analyzing the charac-teristics of inversion resistivity and magnetic susceptibility,effective detection of rock masses and fracture struc-tures was achieved.Application example showed that the airborne magnetotelluric method based on the admittance tensor is sensitive to geoelectric boundary and can be used for detecting near-surface and deep structures in com-plex environmental areas.关键词
