摘　　要：高密度电法具有高效性和便利性,在水工环地质勘探等领域应用越来越广泛,其特点是数据信息量大,观测精度高,生产效率高且电极排列方式可变。本文比较两种不同装置在打井找水及探测隐伏断裂中的应用效果,结果表明,两种装置在勘探不同地质背景下的不同目标时,所得视电阻率响应有所不同,温纳装置勘探深度大且垂向分辨率高,偶极装置横向分辨率高且对异常体反应灵敏。Due to its high efficiency and convenience,the high-density electrical method has been more and more widely used in the fields of hydro-environmental geological exploration.It is characterized by large data information,high observation accuracy,high production efficiency and electrode arrangement variable.Comparing the application effects of different devices in drilling wells to find water and detecting hidden faults,the results show that the apparent resistivity responses obtained by the two devices are different when exploring different targets under different geological backgrounds.The Wenner device has a large exploration depth and vertical high resolution,the dipole device has high lateral resolution and is sensitive to abnormal bodies.
