摘　　要：通过研究基于钻孔数据的三维地质体自动生成技术,基于多源信息约束的地质体自动建模技术以及三维地质体与三维场景数据的融合技术,系统化地提出一套基于多源信息约束的工程地质三维可视化技术理论体系,实现工程地质体与地下管网、管廊、建筑等地下构筑物的无缝融合展示,为地下建设选址、工程施工、区域规划、地质防灾减灾等提供全空间立体三维数据,促进自然资源全域立体空间信息化的发展,服务智慧城市建设。Through the study of automatic generation technology of 3D geological body based on drilling data,automatic modeling technology of geological body based on multi-source information constraints,and fusion technology of 3D geological body and 3D scene data,we systematically put forward a set of theoretical system of 3D visualization technology of engineering geology based on multi-source information constraints,and realized the integration of engineering geological body and underground pipe network,pipe gallery,pipe gallery,etc.The seamless integration display of underground structures such as buildings provides full space three-dimensional data for underground construction site selection,engineering construction,regional planning,geological disaster prevention and mitigation,promotes the development of full space three-dimensional information of natural resources,and serves the construction of smart city.
