Research And Development On Urban Underground Space Integrated Management System Of Futian District In Shenzhen

Abstract:Urban Underground Space Integrated Management is being paid more and more attention to in modern society. Underground spatial data sharing is indispensable for underground space development, which is invisible and secluded relative to overground space development.There are many pipeline information systems, drainage systems and urban geological hazard systems in many cities, which are always manage their own departments only. Due to this reason, much data could not be shared with others. This paper would take the opportunity of integrated development to the underground space of Futian district in Shenzhen. The study looked at30years’ data on geology, underground structure and pipelines in this area, combined with the project of GIS emulated platform in Shenzhen Geotechnical Investigation&Surveying Institute Co.Ltd, then built3D models based on the underground space, according which we carried on the integrated application system in Futian district.This paper followed modern geoscience theory, used SQL server2005to manage the data, SkyLine and AutoCAD to generate three-dimensional models, and published three-dimensional model data with TerrainPush of SkyLine, designed the interface in visible integrated environment of web design, provided by open source framework, SSH.The main job included:establishing geology databases, underground structures databases and pipelines databases, developing and managing the underground space data of different periods and types. To facilitate managing mass data dynamically, we use distributed-integration managemental method, which could update on time. The process of3D visual modeling of geology, underground structure and pipelines is guided by3DGIS technology, modeling method and visualization theory. It realized showing the images and attributes, editing and checking and some other functions, and it also realized the interactive maintenance between the3D geology models, underground structure models and pipeline models. Due to the requests of system design, this paper also introduced the design philosophy and some interfaces. For the requests to application and management of underground space, it prompts the digital project in Shenzhen underground space.The construction and development of the underground space integrated management system established the foundation of the better digital and management of underground space in Shenzhen. And it will provide some decisions in rational exploitation of urban underground space, which is useful for the comprehensive utilization.
