摘　　要：探地雷达作为新兴检测手段,具有高效、快速、无损的优势,但在实际应用中缺乏探地雷达异常体成像判别标准,存在多解性和主观识别问题。为了研究道路中病害的电磁波谱特征,本文以湖北襄荆高速公路作为研究对象,结合GprMax电磁仿真软件对道路结构中的病害体进行雷达正演模拟仿真,以分析不同病害的电磁波场特征。通过雷达正演仿真图像对各病害的雷达波形特征进行分析,结果表明:根据正演模拟中获取的病害雷达图像特征能够为现场雷达图像的解译提供技术支持。Ground-penetrating radar(GPR),as a new detection method,has the advantages of high efficiency,fast and non-destructive,but in practical application,there is a lack of abnormal body imaging identification criteria,and there are problems of multi-solution and subjective recognition.In order to study the electromagnetic spectrum characteristics of diseases in the road,this paper takes Hubei Xiangjing Expressway as the research object,and combines GprMax electromagnetic simulation software to conduct radar forward simulation of diseases in the road structure,so as to analyze the electromagnetic field characteristics of different diseases.The radar waveform features of each disease are analyzed by radar forward simulation images.The results show that the disease radar image features obtained by forward simulation can provide technical support for field radar image interpretation.
