阵列地质雷达在黄河堤防隐患探测中的应用.

In order to detect and evaluate the hidden danger of embankment quickly and efficiently, in this paper, the composition of the vehicle mounted GPR system was analyzed, which was a large array with eight radar antennas. It was suitable for fast carpet full coverage general survey and detection of hidden dangers such as loose dike body, rich water, crack, cavity collapse and so on in large-scale and large mileage river embankment. At the same time, the radar echo characteristics and hidden danger evaluation methods of dam hidden dangers such as loose, rich water and cracks were discussed. At present, 18.2 km preliminary detection application has been carried out on the right bank dike of Huayuankou in Zhengzhou. The technology has high efficiency, convenient working mode and no damage to the dike. Four abnormal points of dike stratum hidden danger have been found in the detection. It is suggested to further confirm and deal with the hidden danger of stratum abnormal points. [ABSTRACT FROM AUTHOR]
