地质雷达在隧道衬砌检测中的应用

隧道施工完成后用常规方法很难对衬砌质量作出系统评价,地质雷达检测以其精度高、快速、无损检测等优点,是近年来发展较为迅速、效果较为显著的隧道衬砌检测方法之一。本文介绍了天线中心频率的选择并通过对几幅典型雷达图像进行分析,介绍了不同的目标特征体在地质雷达剖面上的反映。

It’ s hard to make a systematic assessment of lining quality by the use of routine methods after tunneling is completed.The detection methods of tunnel lining have a relatively rapid development in recent years. Bacause of GPR’s high precision,fast,non-destructive testing and etc,the effect of GPR detecting is more obvious.The paper introdused how to choose the center frequency of antenna.And the paper also introduced different anomalous structures’ representation on radar profiles by made a convenience of some typical radar images.
