摘　　要：介绍了地质雷达探测法的基本工作原理;结合工程实例,将地质雷达探测法应用于水泥混凝土路面板底脱空的判定。首先进行测点选择和雷达参数调节,然后对雷达检测数据进行软件处理,即可判断路面板底脱空的位置,读出脱空点的长度及高度,并能初步判断脱空的原因。数据表明:与落锤式弯沉仪法相比,地质雷达探测法在路面脱空检测中具有更高的可信度;经钻芯复核,检测准确率达80%以上。The basic tenets of the ground penetrating radar detection method were introduced;based on the engineering practice,the ground penetrating radar detection method was used in the cavity detection of cement concrete slabs.Firstly the test points were selected and radar's parameter was accommodated;then the radar's detection data which was coped with software could directly judge the position of the road's voids,read the length and height of cavity,and obtain the preliminary judgment of the cavity reason.The data shows that the radar's cavity detection,compared with the falling weight deflectometer's has higher reliability;with the help of drilling core,the data's accuracy of cavity detection can reach more than 80%.
