探地雷达技术在土石坝渗漏隐患探测中的应用

Application of Ground Penetrating Radar Technique in Hidden Trouble Detection of Leakage in Earth Stone Dam

探地雷达技术作为一种无损伤的探测技术越来越多地应用于大坝、堤防的隐患探测。在介绍探地雷达技术工作原理的基础上,结合实例的探地雷达图像,分析了大坝坝肩存在渗漏通道的图像特征,指出了渗流通道的范围和大小,为大坝的除险加固提供了可靠的依据。

The ground penetrating radar technique taken as a non-invasive detection technique has been more and more applied in the hidden trouble detection of the dams and embankments.On the basis to introducing the working principle of ground penetrating radar technique and combined with the cases of ground penetrating radar pictures,the article analyzes the feature of leakage channel existing in the shoulder of dam,and points out the range and size of leakage channel so as to provide the reliable data for the risk removal and reinforcement of dam.
