摘要
现有的地理信息系统都主要表达二维的地表地物的图形和属性信息,要扩展到真三维包含地下地质结构的地质信息系统还有差距。文章基于GOCAD,分析了工程地质体三维建模关键技术问题,并结合某水电工程坝址区的三维地质建模进行了实际应用。
The existing geographical information system is mainly providing the graphic and attributive information for two-dimensional earth surface, which is different to the true three-dimensional geological information system that contains underground geological structure. Based on GOCAD, the paper analyzes the key technical problems on three-dimensional modeling for engineering geological mass, and makes an intro- duction to practical application of the three-dimensional geo-modeling for the damsite area of a hydropower project.
