摘　　要：研究了双衬层填埋场电学方法漏洞检测的原理.建立了漏洞检测模型,将漏洞电流和回路总电流看成2个点电流源,推导了检测层中电势分布满足的方程,分析结果显示:检测层越薄,同样的检测电流导致的漏洞附近的电势异常越明显,漏洞就越容易被检测出来;检测层厚度有限时,检测电极所在的垂直位置对漏洞的检测定位几乎不产生影响.实验验证了模型的正确性.The principle of electrical leak detection method in double-lined landfills was studied. A detection model was established. In this model, the current flowing through a leak and the source current were regarded as two point source currents. The potential distribution equation was deduced. The thinner the detecting layer was, the more obvious the potential anomaly around the leak was, the easier the leak was detected; the vertical position of the detection electrodes hardly affected the potential distribution when the detection layer thickness was limited. Experiments validated this model.
