近几年，建立水利水电三维地质模型成为地质工作者分析工程地质现象和掌握岩土体结构规律的一种新的有用手段。在CATIA软件的基础上，利用Visual Basic.net编程开发了适用于水利水电行业的三维地质建模平台，系统介绍了该三维地质建模平台，该平台包括覆盖层、地质层、水文层、模型分析、模型剖切、有限元分析等基本模块，结合三维地质建模软件提出了地质模型的覆盖层建模流程；针对建模过程中一些关键技术问题做了详细的分析研究，如原始数据处理、曲面分割、曲面缝合等。同时，该软件可实现对已建好的三维地质模型进行质量检测与修复，以保证地质模型的可靠性，最后利用该建模平台建立了某水电站的三维地质模型，利用平台的切割功能实现模型的任意位置、任意角度的二维剖切，以满足工程设计的需要。

In recent years, building a 3D geological model for water resources and hydropower projects has become a new useful method for geological workers to know layer structure and analyze geological phenomenon. Based on CATIA software, a 3D geological modeling platform is built using Visual Basic.net language, which contains several basic modules, such as overburden layer, geological layer, hydrological layer, model analysis, model cutting, finite element analyses, etc. Based on the 3D geological modeling platform developed by authors, the modeling process for overburden layer is proposed. Some key technology issues are analyzed in detail, such as original data processing, surfaces splitting and surface stitching. Besides, the platforms have the functions of quality testing and repairing work for building 3D geological model which guarantee the reliability of the model. At last, a 3D geological model is built using 3D modeling platform to simulate the geology for a hydropower station. 2D figures can be exported by cutting the model at any angle and anywhere in 3D space to satisfy the designing requirement in engineering.
