Abstract:

Visual and intelligent decision support system based on building information modeling (BIM) and tunnel whole life cycle information is built so as to solve management and decision difficulties of highway tunnel operation and maintenance, i.e. numerous management objects, decentralized information and complex spacetime characteristics, etc. Standardization, visualization and intelligentization are regarded as design principles for the system based on BIM operation and maintenance model. The multisource information integration of design, construction and operation and maintenance of the system can be realized by code standardization and information mapping table. It is composed of 5 layers of perception layer, network layer, data layer, analysis layer and interaction layer. The disease diagnoses and assessment, abnormal detecting and fault diagnosis of equipment and maintenance decision optimization of the system can be realized by intelligent analysis technology. The users can learn the site situation quickly and improve the efficiency and quality of tunnel operation and maintenance through 3D visualization interface of the system. The system has been successfully used in tunnel on Dalian Road in Shanghai and good effects have been achieved.

Key words: highway tunnel, whole life cycle, BIM, tunnel operation and maintenance, decision support system
