集成GIS/BIM的盾构隧道全寿命管理系统研究

A GIS/BIM-Integrated Lifecycle Management System for Shield Tunnel

为解决在盾构隧道工程中,地理信息系统(GIS)标准缺失和建筑信息模型(BIM)分析功能薄弱的问题,在分析GIS的数据管理和BIM的数据标准基础上,建立集成GIS/BIM的盾构隧道全寿命期管理系统。首先,概括总结系统采用的技术路线;其次,基于IFC标准扩展统一的盾构隧道信息模型,涵盖盾构隧道地质、结构、线路、施工、监测和病害等数据;然后,介绍系统信息的关联,包括隧道编码、GIS和BIM的集成方案;最后,以上海地铁盾构隧道为依托,描述系统在工程全寿命期的应用,包括隧道地质勘察、结构设计、运营监测和养护维护等阶段。该系统制定了统一信息模型,方便数据交换和管理,在信息模型基础上实现了信息可视化与不同分析功能,提高了盾构隧道的全寿命数字化管理水平。

In order to solve the problem of the lack of data standard in geographic information system（GIS） and the analysis function in building information model（BIM）,a GIS/BIM integrated lifecycle management system for shield tunnel is built based on the analysis of the data management in GIS and data standards in BIM. Firstly,the technical route of the system is summarized. And then the shield tunnel information model is extended based on the IFC standard,including the information of geology,structure,alignment,construction,monitoring and disease; and an introduction to the information association is presented,including code format of shield tunnel and the integration of GIS and BIM.Finally,the application of lifecycle management of the system is described relied on the Shanghai metro shield tunnel,including geological survey,structural design,operation monitoring and maintenance. The system designs a unified information model to facilitate the data exchange and management efficiency. The functions of the information model visualization and analysis is also developed to improve the digital lifecycle management of shield tunnel.
