Taking hundreds of pieces of hazardous geological maps (1 : 10 000) of Three Gorges res-ervoir area (3GR) as background, we establish regional three-dimensional (3D) geo-hazard modelusing DEM (digital elevation model) superposed surface images and geo-hazards elements. Based on landslides and other geo-hazard survey data,using improved B-REP(boundary representa-tion)entity data structure (two-body 3D data structure), we set up 3D solid models for each hazardous bodies in each hazardous geological maps. Then we integrate the two types of 3D models with different scales from area to point, which are the regional geo-hazard 3D model and the solid models of each disaster body, in order to provide a visual processing and analysis plat-form for danger partition, stability evaluation, disaster prevention and control, early warning and command. 展开更多
