摘　　要：直流电法是近地表探测中最常用的方法之一,该方法具有探测目标准、施工效率高等特点.然而,在野外采集数据时,需要针对不同的探测目标选择不同的装置,这势必会影响数据采集效率.为了选择最优装置,本文通过分析二极装置、三极装置、四极装置对异常体的响应,得出了不同装置的优缺点,并将多种装置的数据进行叠加处理,结果显示多装置响应优于单一装置响应.最后,通过岩溶探测实例说明该方法的有效性.DC(Direct Current)method is one of the most commonly used methods in near-surface detection,which has the characteristics of accurate target detection and high construction efficiency.However,when collecting data in the field,different arrays need to be selected for different detection targets,which is bound to affect the data collection efficiency.To select the optimal array,a series of low resistance anomaly models were established in this paper.Based on the analysis of the responses of pole-pole array,pole-dipole array and dipole-dipole array to abnormal body,the advantages and disadvantages of different arrays were summarized.At the same time,the data of various devices were superimposed,and the results show the responses of multi array to abnormal body are better than single array.Finally,an example of karst exploration is given to illustrate the effectiveness of this method.
