The method of damage depth analysis in the bridge by GPR

摘要

According to the present invention, there is provided a method of controlling a bridge having a concrete slab, comprising the steps of transmitting and receiving electromagnetic waves to and from a bridge having a concrete slab, detecting the intensity of electromagnetic waves transmitted and received with time, analyzing presence or absence of a conductive medium by energy loss of the detected electromagnetic waves, And a linear regression analysis is performed by eliminating the attenuation of the electromagnetic wave according to the nonconductive medium in the linear regression analysis of the depth of the concrete slab according to presence or absence of the concrete slab.
