摘　　要：以连霍高速K1250+200~K1250+500段沥青路面为例,利用调节零点、调节增益、数字滤波、偏移、反褶积等措施处理检测数据,并将探地雷达的检测结果与钻芯法进行对比,发现两者的相对误差均在5%内,且工作效率大大提升,探地雷达法耗费的检测时间比人工钻芯法减少60%以上;分析了沥青路面不同车辙的表现形式,探地雷达的检测数据K1280+320断面的沥青路面右幅外侧车道厚度呈“W”形变化,可判定为失稳型车辙。研究结果表明:探地雷达的检测精度略小于人工法,但工作效率大幅提升,在沥青路面检测中应用探地雷达是可行的。Taking the asphalt pavement of K1250+200~K1250+500 section of Lianhuo Expressway as an example,the detection data are processed by adjusting zero point,adjusting gain,digital filtering,migration and deconvolution,by comparing the detection results of Ground Penetrating Radar(GPR)with the core drilling method,it is found that the relative errors of both methods are within 5%,and the working efficiency is greatly improved,the detection time of ground penetrating radar method is more than 60%less than that of manual core drilling method,the GPR data show that the thickness of the right lateral lane of the asphalt pavement with K1280+320 cross-section changes in“W”shape,which can be judged as unstable rutting.The results show that the detection accuracy of GPR is a little lower than that of manual method,but the efficiency is greatly improved,so it is feasible to apply GPR in asphalt pavement detection.
