摘　　要：水泥路面脱空将导致面层开裂、断板、错台等病害,对行车安全造成极大危害。地质雷达法是利用高频电磁脉冲波的反射探测目标体及地质现象的一种物探手段。通过建立水泥路面脱空的典型模型,运用GprMax2D软件对路面脱空进行数值模拟,结合地质雷达实测和开挖验证,充分说明地质雷达在路面脱空检测中具有准确、高效的特点。Cement pavement cavity will lead to surface cracking, broken slab, staggered platform and other damages, which does great harm to the traffic safety. Ground penetrating radar is a geophysical prospecting means, which is used to detect target and geological phenomenon with the reflection of high -frequency electromagnetic pulse wave. Through establishing typical cavity model of cement pavement, using GprMax2D software to make the numerical simulation of the pavement cavity, combining with the geological radar measured and excavated verification, it shows that the ground penetrating radar method is accurate and efficient in detection for cavity defects of cement pavement.
