摘要
大型复杂建筑项目的实施、环境与自然灾害的评估等都需对地下条件进行精确模拟。由于地下条件的特殊性、地质对象形状的不规则性和属性的各向异性,决定了三维地质建模与可视化的复杂性。在详细阐述三维地质建模与可视化的要求、流程与模型构建的基础上,探讨了三维地质建模与可视化面临的挑战。随着GIS的快速发展、现代信息管理系统的设计优化及IT技术的集成,基于三维GIS的三维地质建模与可视化系统具有十分广阔的前景,与信息管理系统的紧密结合是三维地质建模的未来发展趋势。
A large and complex construction project or an environmental and natural hazard assessment requires a precise definition of subsurface conditions. Due to the special features of subsurface conditions, irregular geo-object shapes and anisotropic properties, the 3D geological modeling and visualization is very complicated. This paper discusses the requirement, workflow and modelling of 3D geological modelling and visualization, as well as related challenges. With the rapid development of GIS, design ideas of modem information management system and integration of IT, the 3D GIS-based 3D geological modeling and visualization is a very promising area of research. The combination with information management system will be the development trend of 3D geological modeling and visualization.
