基于GprMax正演模拟及工程实例的地质雷达钢筋探测研究

A study on rebar detection by using geological radar based on GprMax forward modelling and engineering project examples

通过建立钢筋混凝土模型,利用GprMax软件进行正演模拟,研究了地质雷达钢筋探测受钢筋直径、埋深、间距以及多层钢筋分布等因素的影响情况,提出了多个信号叠加形成的钢筋假象特征与识别方法,并结合工程探测实例进行对比分析。

Through the establishment of reinforced concrete model and forward modelling by using GprMax,this paper studied the effect of factors like diameters,buried depths and spacing of rebars as well as distribution of multilayer reinforced concrete on rebar detection by using geological radar.The authors summarized the characteristics and identification methods of false appearance of rebars which was created by superposition of multiple signals and then conducted an analysis based on engineering detection project examples.
