为解决紫之隧道由于养护工程规模庞大、运维对象数量众多所带来的管理决策困难等问题，引入BIM技术，根据设计图纸和工程实际，通过对BIM软件的二次开发，创建涵盖结构、通风、给排水和供配电等多个专业的紫之隧道工程运维模型。在此基础上，结合网页端三维展示技术，开发B/S架构的紫之隧道运维管理系统，相对于传统的隧道管理方式，该系统具有可视化程度高、空间定位容易、使用方便等特点。系统提供三维展示、定期检查、机电设备管理、监控和监测数据展示等模块，使管理者能在三维场景下，对隧道的病害数据、监控数据以及监测数据有清晰直观的了解。该系统在紫之隧道上的应用，能为保证隧道运维工作质量、提升运营维护水平提供有力的保障。

The management decision of Zizhi Tunnel is difficult due to huge maintenance project and numerous maintenance objects. Hence, the building information modeling (BIM) technology is introduced. And then the operation and maintenance model of Zizhi Tunnel including structure, ventilation, water supply and drainage and power supply is established based on secondary development of BIM software according to the design drawings and engineering practice; and a operation and maintenance system for Zizhi Tunnel based on browser/server (B/S) architecture is developed combining with the web 3D display technology. The system is superior to the conventional management mode in terms of visualization degree, spatialization and usage. The system provides modules such as threedimensional display, regular inspection, mechanical and electrical equipment management, monitoring and detecting data display, so that the managers can have a clear and intuitive understanding on disease data, monitoring data and detection data of tunnel in threedimensional scene. The successful application of the system to Zizhi Tunnel can provide a powerful guarantee for the quality of the operation and maintenance of the tunnel and the improvement of the operation and maintenance level.
