3D GIS地下工程数字化信息系统研究与实现

地下空间时代即将到来,寻求科学规划、设计、管理地下工程的方法和手段成为当今研究热点。基于3D GIS思想,突破传统思维,应时代需求,研发集编辑修改、查询分析、三维漫游展示于一体的地下工程数字化信息系统。采用二、三维一体化技术,同时实现地上、地下空间三维可视化表达和空间分析。改善了以往地下工程信息系统较少涉及地面三维信息化的状况,实现了地上地下信息集成统一;并集成开发了地下结构计算分析模块,实现了隧道、基坑工程配筋设计、稳定分析等功能,并可输出标准设计图纸。其成果可有效辅助地下空间规划、开发和利用。系统开发经验可为其它类似软件开发提供参考。

Research and Implementation of Underground Engineering Geo-digital System Based on 3D GIS

With underground space era coming,it has become the research hotspot to seek for scientific planning,design,management methods and means of underground engineering.Based on 3D GIS,breaking through the traditional method,this study developed a set of editing,query and analysis,3D roam and display in one of digital information system about the underground engineering.In this study,3D visualization and spatial analysis are achieved in the underground space by 2D and 3D integration technology.It improved the condition that underground engineering information system less involved 3D information on the ground in the past,and completed uniform information integration above and below ground.And we also developed the underground structure calculation and analysis module,to achieve a tunnel,excavation reinforcement design,stability analysis and other functions,and can output standard design drawings.The research results can effectively assist the plan,development and utilization of underground space.The experience of systems development can also provide a reference for other similar software development.
