摘　　要：堤防内部的隐患威胁着堤防安全运行，查清隐患部位及其性质对于堤防除险加固具有重要意义。地球物理瞬变电磁法具有分辨率高、探测速度快、操作简便、没有插入地下的电极等优点，适合于堤防隐患和渗漏探测的特殊要求。作者研制成功一系列堤防和土坝隐患渗漏探测专用瞬变电磁仪。本文介绍瞬变电磁法工作原理及ＳＤＣ－３型堤坝渗漏探测仪在现场应用情况。Hidden defects threaten safe operation of levees. In the removal of flaws from levees and strengthening of levees it is important to detect the position of hidden defects and their features. The advantages of Transient Electro-Magnetic Sounding (TEM) of geophysics are high resolution, fast detection, easy operation, and no electrodes into earth. This technique is suitable for detection and positioning of hidden defects and leakage in levees. The authors have developed a series of special instruments based on TEM for this purpose. In this paper, discussed is the principle of TEM used in levees, and application of Type SDC-3 Levee leakage detector.
