基于Voxler的高密度电法数据三维可视化的实现

The realization in 3D visualization of high-density resistivity method data based on Voxler

高密度电法在工程物探方面有广泛的应用,它是以地下岩土介质的导电性差异为基础,通过观测和研究人工建立的地下稳定电流场的分布规律,反演地质结构。Voxler是一种简单易操作的三维可视化成图软件,通过Voxler软件对高密度电法数据进行三维可视化处理,得到三维切片图、三维插值图。高密度电法数据的三维可视化处理,相比于二维反演图更直观,立体显示物探成果,布线方式相比于真三维采集数据要求较低,成本也较低,让工程人员更加轻松直观地了解地质体结构规律和工程地质情况,更有利于对物探结果的解译。

High-density resistivity method is one of the key technologys in engineering geophysical exploration.It is based on the uneven distribution of electrical conductivity of the underground rock and soil,and back-analyzes the geological structure by observing and studying the distribution of underground steady electric current field.Voxler is a 3D visualization mapping software which is easy to operate.Through the 3D visualization processing of Voxler software to high-density resistivity method datas,we can get the 3D slice figures and the 3D interpolation figures, which are more conducive to be used to analysis and study the geological exploration results, comparing to 2D inversion figure.And it has lower requirements and lower costs, comparing to collecting 3D datas.It is more conducive for engineers to understand the structure rules of geological body and geological conditions and also more advantageous to the interpretation of the result of the geophysical prospecting.
