Comparison of Anti-Noise Performance Using Wenner and Dipole-Dipole Arrays in Pollution Survey

  • 摘要: 为比较2种电阻率法污染场地探测装置——温纳和偶极装置的抗噪声性能,基于点电流源电场分布原理进行理论推导,研究了理想均匀半空间的理论电位取值,并在重庆一废弃化工厂进行实际场地探测比较. 结果表明,采用相同极距的2种探测装置,温纳装置采集的信号强度为偶极装置的3倍以上,具有更强的在抗噪声性能. 在实际探测中,温纳装置仅有0.28%的数据由于数据质量较差被移除,而偶极装置的这一数据占12.10%,可见温纳装置比偶极装置具有更好的抗噪声性能. 因此,在实际污染场地探测中,如果场地的噪声干扰严重,应优先选择采用温纳装置进行探测.
