摘要:
针对地下空间与工程的信息化,采用GIS技术、图形学技术、数据管理技术、数据分析技术、网络通信技术等,提出数字地下空间与工程的概念,旨在建立高度综合的、统一的、开放的和一体化的地下空间与工程信息系统,涵盖地表、地层调查、设计、施工、监测、检测和运营管理等内容。着重讨论了数字地下空间与工程数据库模型建设的方法和技术,并通过一工程实例说明了数据库模型的应用。数字地下空间与工程数据库模型建设对三维空间查询、工程施工模拟、工程全生命周期管理、实时监测和数据挖掘等工作提供支持;对地下空间的可持续发展也将起到积极的作用。
Abstract:
Based on the extensive development of underground space and project,the concept of geo-digital underground space and project(Geo-digital) was presented by use of technology of GIS,graphics,database,numerical analysis and network communication.The target was to establish a high integrative,exoteric and incorporative geo-digital information system which included the geography,stratum investigation,design,construction,monitoring,project detection and operational maintenance.The method and technology to create geo-digital database model were mainly discussed and an example was demonstrated for its application.Geo-digital database model would support spatial inquiry,constructing process simulation,project lifecycle management,real time monitoring and data mining,etc.Furthermore,it would not only play an active role in the sustainable development of underground space,but also bring great economic benefits.
