【摘要】 向家坝水电站是金沙江流域水电开发中的重要控制性工程。该工程地质构造复杂,勘测数据庞大,地质工作者很难对其工程岩土体的分布规律有一个整体和直观的把握。为了适应这一当代巨型水电工程建设的需要,作者利用虚拟现实技术(VR)与三维建模技术,建立了向家坝VII坝址虚拟漫游信息系统(VRGIS),实现了对坝址区三维地质模型的手动和自动虚拟漫游,对地层、断层、水位面的实时查询,对模型的任意切剖、输出等功能,这对直观地反映场地地质信息的分布,整体把握场区地质构造辅助工程决策具有积极意义。该套系统在向家坝水电站的成功应用表明,其应用前景十分广阔。更多还原

【Abstract】 Xiangjiaba Hydropower Station is a representative project in Jinsha River area. As the geological struc-ture is greatly complicated and the amount of exploring data is extremely immense, it is difficult for the geologists toclearly explain the whole information of the exploring data and to directly hold the distributing rule of the rock andsoil in engineering. In order to answer the call for constructing gigantic hydropower stations, the authors have set upthe VRGIS of VII dam site of Xiangjiaba Hydropower Station with the VR technique and 3D modeling technique.Flying interactively or automatically in the 3D virtual environment, the operator can directly and conveniently obtainthe information of three-dimensional geological models, such as strata, faults, water level, etc.. In this way, themanager can grasp the geological structure on the dam site, improve the correctness of analysis, and make a strate-gic and proper decision. The application of VRGIS to the Xiangjiaba Hydropower Station shows that it has a flourishprospect.更多还原
