摘　　要：大型水利水电工程所处地区地质构造复杂,涉及的地质信息众多且时间跨度长,给工程设计带来很大的困难.基于锦屏一级水电站工程实例,通过对地质勘探数据的整理和对地质解译结果的分析,采用新的方法和数据结构建立了满足要求的三维地质模型.进而以三维地质模型为中心,从点、面、体 3个层次将空间图形与其信息进行有机链接,同时也建立了相关的综合地质信息数据库,实现了三维地质模型信息的可视化管理与查询,突破了传统的纯文本方式,使工程人员能够全方位、动态地分析和利用地质信息,提高设计水平.Due to the complicated geological structures,numerous related information and long time span, there are great difficulties during the engineering design of large-scale hydropower projects. Based on geo-exploration data and interpretative results of Jinping first-level hydropower engineering, 3D geologic model is established by a new method and hybrid data structures. Then, centering on the 3D geologic model, the spatial graphics are linked with their attributes organically from three hierarchies of points, surfaces and bodies. In addition, the integrated database of geologic information depended on the model is also set up. Therefore, the (visual) management and query of 3D geologic model information could be operated. It breaks through traditional mode of plain text and improves design in practice, for engineers to analyze and utilize geological information fully and dynamically.
