重大工程地下空间信息系统开发应用及其发展趋势

Developing Trends of Underground Spatial Information System in Major Projects

地下空间信息系统(USIS)是当前岩土工程研究中的一个重要发展方向。介绍了建立地下空间信息系统的目的和意义,论述了USIS的开发方法及其关键技术,包括:数据库技术、界面实现技术、MAPGIS二次开发技术、OpenGL三维图形开发技术、数字制图与智能分析技术等,并结合东深供水改造工程地下空间信息系统进行了开发方法和关键技术的应用研究,最后,对USIS的发展趋势作了较深入的分析,指出了今后研究的几个主要方向。

For the moment, underground environment information system is one of the main developing fields in the research of geotechnical engineering.Firstly, on the introduction of establishing underground environment information system (USIS) is concentrated. And then, the exploitation methods and the key techniques of USIS, including data base design, main surface realization, MAPGIS secondary development, OpenGL 3D mapping techniques and digital mapping and intellective analytical technology, are discussed. By combining the techniques with the developing practice in the Underground Spatial Information System of Water Supply Improvement Project from Dongguan to Shenzhen, the developing trends of USIS is analyzed. Finally, the authors put forward some new trends of USIS in the future.
