摘要: 高密度电阻率法是一种阵列式的勘探方法，具有采集观测数据量大、地质信息丰富、生产效率高等特点，数据采集多以剖面形式工作，成果多为二维反演结果，资料处理过程中经常出现局部畸值或相邻测线对照一致性差等问题.为解决该问题，本文在探查采空区分布和巷道位置的工作中，结合剖面数据采集特点提出非规则“#”剖面布设勘探法来补充纵向数据信息，并通过三维可视化软件建立以高密度电法电参数为依据的地质体模型，实现高密度电法数据场三维可视化和实际应用.Abstract: High-density resistivity survey is an array type of exploration method, characterized by large amount of observation data, rich geological information and high work efficiency. Because the data are mostly collected from sections, with results from two-dimensional inversion, it is common for local abnormal values or inconsistency of adjacent line control in data processing. In order to solve such problems, this paper puts forward in the irregular "#" section layout exploration method to supplement data in crossing direction. With 3-D visualization software, a geological model is set up on the basis of high-density resistivity survey parameters to realize the 3-D visualization of high-density resistivity method in the application of subduction exploration.
