应用自然电场法检测土坝渗漏隐患的技术

笔者根据在全国各地进行的数十座水利工程的原位测试资料，概括归纳出一套较为系统的应用自然电场法检测土坝渗漏隐患的技术，该技术将集中渗流在自电电位曲线上的反映归结为窄幅异常、宽幅异常、宽幅双峰异常、多峰异常和塔式异常五种基本形态，并可正确地判断正常渗漏和异常渗漏，解释推断出集中渗漏带的宽度、埋深、走向以及渗流的时空动态，为工程除险加固提供可靠的技术资料.

The technique to detect the leakage of dam by applying the spontaneous electric field

According to the primitive test data of marine hydraulic engineering in all of the country, the writer generalizes a set of technical system to detect the seepage of darns by the method of Spontaneous Electric Field. From the reflecting of leakage in the electricity curve, the technique will be concentrated five kinds of basic appearances that are the narrow difference, the breadth difference, the double breadth difference, some difference and the difference as a tower. It not only can judge the natural leakage and the exceptional leakage, but also can explain and predict the seepage space of which the width, the depth, the direction and the flow changing with the time. Above all, the technique would be offering the dependable data for the reinforce engineering in the future.
