| 摘 要： | 水坝渗漏的成因较为复杂 ,通过物探方法检测可为分析研究坝体渗漏的原因以及采取相应的加固措施提供依据。渗漏部位因介质含水量的变化产生电性异常 ,为地质雷达方法的应用提供了有利条件。渗漏现象使雷达波幅频特性发生变化 ,对雷达图像的分析可以确定渗漏的部位和埋深。实践证明 ,地质雷达方法在水坝渗漏检测中有较好的应用效果

| Abstract: | The causes of leakage of dam are very complicated, using the geophysical methods to detect the dam can be helpful to analyse the causes and can provide the suggestions for consolidating the dam. Since the electric anomaly caused by the change of the water content due to the leakage can be detected by GPR. The leakage would make the amplitude-freguency characteristic changing. The position and depth of the leakage can be determined by analysing the GPR data. The case presented in this paper proved that GPR method is a effective way to detect the dam leakage. |
