摘要
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; and 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.
