基于gprMax正演分析的道路质量与病害探地雷达探测
Ground Penetrating Radar Detection of Road Quality and Disease based on gprMax Forward Analysis
摘要
Abstract
With the development of society and the acceleration of urbanization,urban road safety has become a focal point of attention.In this study,Ground Penetrating Radar(GPR)was utilized as an efficient geophysical method to investigate the detection of road quality and defects on a large scale in urban areas.A numerical simulation software,gprMax,based on the Finite-Difference Time-Domain(FDTD)method,was employed to simulate the electromagnetic wave propagation and perform geophysical forward modeling of common road anomalies and defects in urban environments.By analyzing the generated B-scan radar profiles and visualizing the geometric models,the radar re-sponse characteristics of different anomalies and defects were studied and analyzed,providing guid-ance for the data analysis and interpretation of practical road GPR surveys.Finally,by integrating actual data collected from road GPR surveys in Nanchang city,a road quality assessment was con-ducted,and potential defect types were identified.The results indicated that this method effectively served the detection of urban road quality and defects using GPR,providing an efficient approach for improving urban road quality and defect investigations.This research holds significant importance in addressing the increasing challenges of urban road safety.关键词
