Application of Expert System in Transient Electromagnetic Inversion

Database inversion expert system is developed by using VB as the development tool,and using forward calculation parameters and transient electromagnetic responses,which for water-rich Karst cave and hydrous fault in front of a tunnel is obtained through numeric simulation calculation,as expert samples.On the development platform of Matlab,neural network expert system is established through programming.Load LSSVM function into Matlab to realize LSSVM expert system through programming.Application of the 3 expert systems in actual projects indicates:When transient electromagnetic method is used to probe geoelectric structures of water-rich abnormality in front of a tunnel,the accuracy of inversion by the expert system is sufficient for the requirements of a project.
