摘要
探地雷达检测是一种无损检测方法。混凝土建筑结构内部通常都有钢筋网支撑,由于金属介质对高频电磁波存在强反射现象,因此使用探地雷达进行建筑结构检测非常适宜。通过分析探地雷达剖面,可判断建筑结构内部钢筋位置及分布状况。通过钻孔验证,GPR测试结果与污水处理池底部实际情况一致。
Ground Penetrating Radar （GPR） is a non-destructive testing method. The inside of concrete building structure is usually supported by steel mesh,for strong reflection of metal medium to high frequency electromagnetic waves,the use of ground penetrating radar （GPR） is very suitable for structural testing. Through analyzing GPR profiles,location and distribution of steel inside the internal structures of the buildings can be determined. Through the drilling verification,GPR detection results are found the same as the actual situation of the bottom of sewage treatment pond.
