摘　　要：堤坝疏松是水利工程中常见的一种工程灾害,它对堤坝安全带来了极大的安全隐患。而探地雷达法具有无损、高效、精准的特点,因此越来越多的被应用于堤坝安全检测中。本文在介绍探地雷达的基本原理上,结合实测地质雷达图像,并通过现场静探验证,分析并指出堤坝疏松区域在地质雷达图像中的异常特征,为堤坝防护治理设计提供可靠的依据。Dam loosening is a commonly-seen engineering disaster in irrigation works and poses a great danger to dams. Ground penetrating radar is non-destructive, highly efficient and accurate, and becomes more and more poplar in dam safety test. This paper introduced the principle of the radar, showed measured geological radar image, performed static sounding test on the spot, analyzed anomalous features of the loosening areas of dams on the radar image, and provided a reliable basis for design, protection and treatment of dams.
