摘　　要：GOCAD是主要用于地质领域的三维可视化建模软件,具有强大的三维建模、可视化、地质解译和分析功能。基于CAD技术和大量编程经验,借助CAD图形环境平台,进行多源地质资料分析和耦合,建立了贵州安顺坝陵河大桥西岸地质体的三维模型,并将GOCAD模型转化到CAD模型中,使CAD将属性信息附着于图形,进而从图形上获知整个区域的属性分布,并清楚地显现出来。The GOCAD is a 3D visualization modeling software mainly used in the field of geology, with a powerful 3D modeling, visualization, geological interpretation and analysis functions. It provides multiple restrictive functions, facilitating the arbitrary surface shape edit, accurately simulation of terranes trends and mutual contacts relationship. Combined with the thorough understanding of CAD technology and a lot of programming experience, with the help of CAD graphics environment platform to analyze and couple multi-source geological data, the au- thors establish a 3D geological model of some stratum, in Guizhou Province and also explore to transform GOCAD model into a CAD model, resulting in attribute information can be attached to graphics in CAD and attributes of the entire region can be derived and showed clearly, which can provide direct reference for engineering workers to design and layout project.
