　　在浅覆盖区地质调查中，钻探和物探等方法常用于揭示地质体三维空间分布。本文借用三维可视化方法，以运漕幅作为研究区域，利用钻孔资料和人工解译的地质图快速构建第四系三维地质结构模型，以展现研究区第四系宏观地层格架。文中详细介绍了模型构建的数据源及流程。最后，结合虚拟勘探线剖面成果模型，探索以立体形象的方式显示区域地层分布。所构建的第四系模型可称之为三维地质图，其价值即体现在形象的展现地质体空间分布。

During geological survey in a shallow overburden area,drilling and geophysical methods are usually used for unveiling 3D spatial distribution of a geological body. This paper,by aid of 3D visualization method,based on drilling data and interpreted geological maps,quickly builds 3D geo-structure model of the Quaternary system in the Yuncao map area to display the macro stratigraphic framework of the study area. The data source and process for model build-ing are described in detail in this paper. Finally,with the virtual exploration line profile result model as a reference,a try was made to display regional stratigraphic distribution in the form of 3D. The constructed Quaternary system model can be seen as a 3D geological map,the value of which is to visually show the spatial extension of a geological body.
