摘 要: 以钢筋混凝土板为研究对象 ,通过雷达波无损检测试验 ,对雷达波成像图形进行信号分析 ,得出钢筋、孔洞以及密实度在雷达波成像图形中的特征并做出识别 。 As a new and advanced testing method, the GPR(Geological Probing/Penetrating Radar)technique is highly efficient,nondestructive,and of high resolution.One problem for its application in reinforced concrete is the evaluation of images obtained.Presently,a reinforced concrete plate with defects is studied with the technique.The image characteristics of steel bar and the defects are shown.
