Direct current (DC) resistivity method is one of the means to explore karst areas, which has the advantages of a precise exploration target, high construction efficiency, and powerful anti-interference ability. However, the types of DC resistivity method arrays are complex, in situ exploration, different arrays are suitable for different exploration targets, which will greatly affect the construction efficiency. By generating anomaly bodies to demonstrate the various reactions of various arrays, this study compares and contrasts the benefits and drawbacks of the pole–dipole array and the Wenner array. The findings demonstrate that the Wenner array has a relatively shallow exploration depth, a reasonably good effect on surface-level anomaly identification, and a poor effect on deep-level anomaly detection; pole–dipole array has relatively large exploration depth and relatively high resolution to the deep anomalous areas. Based on this, a new data type known as multiple array data is incorporated by superimposing the data from two arrays. The following inferences are made from the inversion results: multiple array can not only retain the maximum investigation depth of single arrays, but also respond to anomalous areas better than any single arrays. Moreover, the reliability of multiple array data is further verified by an example of limestone exploration, therefore providing basis for field survey.

直流电阻率法是岩溶地区勘探的手段之一，具有勘探目标精确、施工效率高、抗干扰能力强等优点。然而，直流电阻率法台阵类型复杂，原位勘探中，不同的台阵适合不同的勘探目标，这将极大地影响施工效率。本研究通过生成异常体来演示各种阵列的各种反应，比较和对比了极偶极阵列和温纳阵列的优缺点。研究结果表明，Wenner阵列探测深度较浅，对地表异常识别效果较好，深层次异常检测效果较差；极偶极子阵对于深部异常区域具有较大的探测深度和较高的分辨率。在此基础上，通过叠加两个数组的数据来合并一种称为多数组数据的新数据类型。根据反演结果得出以下推论：多阵不仅能保留单阵的最大探测深度，而且比任何单阵都能更好地响应异常区域。此外，通过石灰岩勘探实例进一步验证了多阵数据的可靠性，为现场勘察提供了依据。根据反演结果得出以下推论：多阵不仅能保留单阵的最大探测深度，而且比任何单阵都能更好地响应异常区域。此外，通过石灰岩勘探实例进一步验证了多阵数据的可靠性，为现场勘察提供了依据。根据反演结果得出以下推论：多阵不仅能保留单阵的最大探测深度，而且比任何单阵都能更好地响应异常区域。此外，通过石灰岩勘探实例进一步验证了多阵数据的可靠性，为现场勘察提供了依据。
