Design and Implementation of Urban Three-dimensional Underground Space Management System
With the rapid development of urbanization,the above-ground space in cities is becoming increasingly scarce,and the de-velopment and utilization of underground space has become an inevitable choice for urban development.In order to meet the require-ments of informatization and refined management of urban underground space,this article uses GIS,3D visualization,and BIM tech-nology to study the construction method of urban 3D underground space management system.The system construction ideas,framework design,and functional realization are proposed,and the problems encountered in the system development process such as 2D and 3D linkage and 3D dynamic loading are analyzed and solved.The functions of integrated display of 2D and 3D in urban underground space,underground application management,BIM application management,etc.are realized,providing technical support and auxilia-ry decision-making support for the development and utilization of urban underground space.
