运营地铁隧道多源测试信息集成与安全管控平台研究

Research on integrated platform of multi-source information integration and security management for metro tunnel in operation

近年来,城市地铁隧道结构长期健康问题日益凸显,全面、及时掌握地铁隧道结构安全影响要素信息,实现数字化、可视化及智能化管理已成为必然选择。本文结合软土地区城市地铁结构维护管理需求,采用建筑信息模型(BIM)、地理信息系统(GIS)技术、虚拟可视化等多种信息技术,通过构建二、三维一体化平台,实现隧道地质、结构、监测、巡视等多源测试信息的融合,为运营地铁隧道维护管理工作提供必要的技术手段。

The long-term structural health problems of urban metro tunnel have been rising in recent years.Comprehensively and timely grasping the information of safety influence factors and realizing the digital,visualized and intelligent management have become the inevitable choice.Combining with the requirements of structure of urban subway safety management in soft soil area,based on the techniques of information model(BIM),geographic information system(GIS)and the virtual visualization,this paper builds anintegration platform of 2 D&3 D system which integrates the multi-source testing information of geology,structure,monitoring and inspection,and provides necessary technical means for the maintenance management of metro tunnel.
