摘　　要：通过对沭阳主城区水文地质条件以及水文地质钻孔资料的分析,利用GeoDatabase空间数据库与OpenGL图形库,使用B-Rep模型构造水文地质含水层结构的三维模型,实现了包括旋转、平移、缩放、属性查询等三维模型浏览功能,展示了沭阳主城区三维水文地质结构整体形态和单个含水层的三维结构以及对含水层的任意切割剖面与三维可视化栅栏图,从而更加直观的反应沭阳主城区地下水的赋存条件与赋存空间的三维可视化效果和可认知程度,为沭阳主城区地下水资源管理和利用提供依据。Based on the analysis of hydrogeological conditions and borehole data,a three-dimensional model described the aquifer structure of Shuyang main city zone is set up,by utilizing GeoDatabase,OpenGL graphics library,and B-Rep model.It can realize so many browsing functions,such as rotation,translation,zooming and attribute query.This three-dimensional model not only displays the integral form of 3 D hydrogeological structure of Shuyang main city zone,but also shows 3 D structure of a single aquifer.Moreover,any cutting profile of an aquifer and 3 D visual grids can be also exhibited.It is a meaningful tool to directly reflect and visualize the occurrence conditions of the groundwater in Shuyang main city zone,which can provide evidence for managing and using groundwater in this place.
