Analysis and Thought about Technology and Method of Locating Deeply Buried Gas Pipes under Overpass

摘要

Underground pipe detecting theory and technology using FDEM method is sketched with discussing the detecting of two pieces of deeply buried pipes inside which are flammable and explosive material.In this case specified countermeasure is taken to challenge the real problem and to improve general signal-to-noise ratio to acquire better samples.Computer inversion algorithms are also employed in explanation the case and they consist with each other well.Compared to feature point method,Computer inversion algorithms shows its advantage.
