探地雷达在嘉兴市非金属管线探测中的应用

Application of Earth-detection Radar in Nonmetal Pipeline Detection of jiaxing

介绍了探地雷达的工作原理及方法,分析了地下目标体的雷达波组特征,总结了探地雷达深剖面图的异常特征。经开挖验证,探地雷达异常特征与地下目标体实际位置相吻合,说明该方法具有速度快、探测精度高、可获得连续结果等特点。

The authors briefly introduced the operating principle of GPR and its method and technique forinvestigating the subterranean cavitation, analyzed the radar wave group characteristics of subterranean cavitation, and summarized the anomaly characteristics of the time--depth sections of the GPR.The excavation verifies that the anomaly characteristics of the GPR accord with true position of the subterranean cavitation.The method has the charae.teristics such as high speed and precision as well as available sequential results.
