摘　　要：三维高密度电法勘探工作成本低、效率高、信息丰富、解释方便,其结果能够直观地显示目标异常体的走向、空间位置和形态等,被广泛应用于隐伏断裂、岩溶、滑坡、考古、尾矿库隐患探查监测及其他工程项目。本文应用Res3Dinv4.0软件对已采集的宝鸡市凤翔区高密度电法勘探数据进行三维反演研究,获得了区内电阻率的空间分布特征,并根据周围地表情况和地质资料推断出了区内的渗流通道位置,为区内研究地层地球物探特征提供了可靠的基础资料。Three-dimensional high-density electrical prospecting method is featured in low-cost,high-efficiency,rich in information and easy to interpret,the result of which can intuitively display the direction,spatial position and morphology of the target anomaly and is widely used in detection and monitoring of buried fault,Karst,landslide,archaeology,hidden danger possible in tailing pond and other engineering projects.In this paper,Res3Dinv4.0 software was used to study the high-density electric method exploration data collected from Fengxiang County,Baoji City,obtaining the spatial distribution of resistivity in this area.According to the surrounding surface and geological data,the location of seepage passage in the area is inferred,which provides reliable basic data for the study of geophysical characteristics of strata in this area.
