济南泉域重点地段可视化三维地质模型建立

为深化对济南泉域的认识，运用已有钻孔、地质图、地形图及剖面图等多源地质数据，通过对钻孔数据、地质边界、DEM数据、断层数据以及辅助数据等多源数据进行耦合，对剖面进行CAD设计以完善空间信息，建立了济南泉域钻孔模型、断层模型、层面模型，采用Horizons-to-solids方法实现了实体模型的重构，最终完成了济南保泉三维地质建模。该模型实现了空间信息全方位、一体化显示，刻画了地质对象之间复杂的空间关系，解决了地质空间数据的查询、分析、计算与管理，为济南保泉工作提供了有力的地质依据。

Establishment of Visualized 3D Geological Model in Key Sections in Jinan Spring Region

In order to deepen the understanding of Jinan spring area, by using the existing drilling datas, ge- ological maps, topographic maps and profile maps, through coupling of borehole datas, geological bounda- ries, DEM datas, fault datas and multi - source datas, CAD design has been carried out to improve the spatial information of profiles, and drilling model, fault model, the level model of Jinan spring region have been set up. By using the Horizon - to - solids method, the reconstruction of the entity model has been re- alized. Thus, final three - dimensional geological model of Jinan spring protection has been finished. The model has realized comprehensive and integrated display of spatial information, depicted the complex spa- tial relationships between geological objects, solved geological spatial data query, analysis, calculation and management. It will provide a strong geological basis for the work of Jinan spring protection.
