According to tunnel characteristics, it is recommended to adopt a combination of multiple technologies for modeling to ensure model quality and application effects
Directly utilize BIM models from tunnel design and construction stages, perform lightweight processing and format conversion through professional engines, which can maximize the retention of structural relationships and semantic information, achieving seamless connection from construction to operation.
For tunnels that have been built but without BIM models, laser scanning technology is used to obtain high-precision point cloud data, reverse-generating reality 3D models consistent with the entities, with high precision and good restoration.
Conduct supplementary manual modeling for specific equipment and newly added facilities that cannot be covered by BIM and scanning, ensuring the completeness and accuracy of the model.
Models need to meet the high requirements of tunnel operation for safety, accuracy and real-time performance
Models must be built strictly according to 1:1 scale, accurately reflecting the internal space, pipeline arrangement and equipment positions of the tunnel, which is the basis for spatial measurement, collision analysis and emergency simulation.
Tunnel models are long and narrow with complex interiors, and must undergo efficient model face reduction, LOD (Level of Detail) processing and instantiation optimization to ensure smooth loading and rendering on the Web. Models need to be logically layered and managed according to "structure-profession-system".
Model objects must have clear classification and coding (such as classification by power, water supply, communication and other professions), and each equipment component must be given unique ID, model, parameters and other attributes, facilitating association with IoT data and asset information.
Models need to support seamless first-person roaming, pipeline transparency, equipment information query, area sectioning and other interactive operations to meet the needs of virtual inspection.
In the tunnel visual operation monitoring system, the 3D model serves as a unified spatial information base, which can be deeply integrated with multiple core subsystems
Real-time binding and display of temperature and humidity, gas concentration, water level and other sensor data on the model, as well as the equipment status of fans and water pumps, to achieve visual early warning and linkage control of environmental risks.
Associate cameras, access control, intrusion alarms and other equipment with the model, achieve rapid linkage of "click model, retrieve video", and accurately locate alarm events in 3D space.
Bind various pipeline models with their operating parameters (such as power cable temperature, current carrying capacity; water supply pipeline pressure, flow rate) to achieve real-time visualization and over-limit early warning of pipeline operating status.
Plan and display robot/manual inspection routes in the model, track inspection positions in real time, and directly mark and report hidden dangers found (such as pipe support displacement, leakage) in the 3D model.
Associate equipment ledger and maintenance records to achieve visual asset management. In case of emergencies (such as fire, leakage), quickly locate the accident point based on the model, view the surrounding environment, simulate disaster impacts, and efficiently dispatch emergency resources.
Through the above methods, the 3D model will completely change the "black box" state of utility tunnels, achieving transparent, intelligent management and safety assurance of underground lifelines, providing strong technical support for urban infrastructure operation.
