摘　　要：偶极子间距会对电法检测填埋场漏洞的灵敏度和准确度产生影响。基于电法检测填埋场渗漏的原理,对偶极子间距的影响进行了分析及实验验证。理论及实验结果表明:偶极子间距越大,漏洞检测的灵敏度越高,但定位准确度同时降低且易造成漏检;偶极子间距越小,漏洞定位的准确度越高,但检测灵敏度降低。工程实践中,偶极子间距通常确定为1 m。The dipole spacing could affect the detection sensitivity and accuracy in the electrical landfill leakage detection.Based on the principle of electrical method,the influence of dipole spacing was analyzed and validated by experiment.The theoretical and experimental results show that：（1） the greater the dipole spacing is,the higher the detection sensitivity is,but the locating accuracy lower and some leaks will easily be undetected;（2） the smaller the dipole spacing is,the higher the leak locating accuracy is,but the detection sensitivity lower.In engineering practice,the dipole spacing usually is determined as 1 m.
