Emulation Calculation on the Magnetic Property of Engineer Obstacles in shallow Water

Regarding the engineer constructed obstacles included the steel rail in shallow water as the research target, starting with the analysis on the material characteristic and the magnetic property of the steel rail, this article sets up a magnetic field calculation model of this type of specific engineer obstacles by use of quantitative geognosy. Based on the emulation calculation, the article puts forward the key design parameters and the detailed method in which the engineer obstacles were detected effectively by using the magnetic fluxgate gradient detection technology. The result of the emulation calculation dovetails with the value of the actual testing, and the design scenario, which is put forward in accordance with the result of the emulation calculation and the actual testing, is validated in the course of engineer development phase sufficiently.
