摘　　要：目前三维高密度电法技术研究大部分集中在二维成果三维可视化方面,对真三维高密度电法技术研究相对较少,且偏向于数值模拟研究,缺少实测数据支撑。针对上述问题,在武汉市江夏区某地开展野外试验,对同网格排列下的组合三维与真三维实测数据体结构特征及其三维反演可视化成果进行对比分析。结果表明,真三维高密度电法在二极装置全测量方式下观测到的数据量远大于组合三维,三维反演成果细节刻画更为细腻。建议将真三维高密度电法技术作为一种精细化探测技术在工程中推广应用。At present,most of the research of 3D high-density electrical method(HDEM) technology focuses on 3D visualization for 2 D results,preferring to numerical simulation,less on Real 3D HDEM technology,and lack of measured data support.In view of the above problems,the author selected a block of field to carry out test in Jiangxia District,Wuhan City,and compared and analyzed the data structures,3D inversion and visualization results,respectively from Combined 3D and Real 3D HDEM measured data under the same grid arrangement.The result shows that the volume of data acquired by Real 3D HDEM is much larger than that by Combined 3D HDEM under the full measurement mode of the pole-pole array.3D inversion results can depict more details.It is suggested that the true three-dimensional high-density electrical method should be popularized and applied in engineering as a fine detection technology.
