中文摘要：

高分辨电阻率法采用单极一偶极装置，对老窑等地下洞道非常敏感，可以提供快速、准确、直观的成像反演解释方法．为进一步提高探测的准确性、避免旁侧影响，将单极一偶板装置以网格方式布设在地面上进行面积测量，在纵横两个方向都形成对地下分析分辨单元的多次覆盖观测，实现三维电阻率勘探．在三维高分辨电阻率探测中，直接成像解释方法仍然有效，获得的地下洞体的位置和影像更为精确．

英文摘要：

The pole-dipole array high resolution resistivity method is very sensitive to underground cavities such as old mine areas, and can provide rapid, accurate and visual interpretation technique to realize imageing. In order to improve the accuracy of detection and avoid the bystander.effect, the pole-dipole arrays are laid in the mode of grid to carry out real measurements. The electrodes are arranged and combined properly to realize multiple coverage for measurements of the underground target cells in vertical and horizontal directions. So the three-dimensional resistivity exploration is implemented. In the three-dimensional high-resolution resistivity detection, direct imaging interpretation method is still effective and the obtained position and image of underground caves are more accurate.
