Abstract
The present invention relates to a correction method for transient electromagnetic method-based prediction of water-bearing structure ahead of tunnel wall, which pertains to the technical field of transient electromagnetic sounding method. The correction method includes a method for eliminating effects of transition process in a reception probe and a method of using earth conductivity to eliminate effects of transition process. By using the correction technique, more accurate information about the location, size and shape of the object in front of the tunnel wall can be obtained, which is of great significance to the study of the fine water-bearing geological structure.
