Cross-sea transportation infrastructure is characterized by large engineering scale,and high construction complexity.There are still some key problems in traditional operations and maintenance work,such as high comprehensive cost,low efficiency,poor accessibility,and large offshore safety risks.In order to realize the safe,reliable and efficient operation and maintenance of the Hong Kong-Zhuhai-Macao Bridge(HZMB),four common problems of the sea-crossing transportation infrastructure are summarized:low perception ability of service status,low utilization rate of monitoring information value,low efficiency of traffic risk active management and control,and low level of informationization and intelligent decision-making in operation and maintenance management.This paper analyzes the key technologies of intelligent operation and maintenance of the HZMB,and refines nine construction contents of intelligent operation and maintenance of the HZMB:the cross-sea traffic infrastructure operations based on 5th Generation Mobile Communication Technology(5G)and Internet of Things(IoT),the millimeter deformation monitoring and closed space positioning based on Beidou,the intelligent monitoring platform and big data fusion processing system for underwater structure,the inspection,testing,integration of emergency system based on unmanned aerial vehicle,the proximity detection and maintenance system for cross-sea bridges and tunnels based on the inspection robot,the service environment digitization and operational status monitoring and evaluation system for cross-ocean cluster facilities,the digital maintenance and management system for cross-sea cluster facilities based on the life-cycle hypothesis,the intelligent system of full-time traffic safety operation and rapid emergency response,the integrated operation and are summarized management platform for cross-sea cluster facilities.In addition,the overall technical architecture including device awareness layer,communication layer,basic resource layer,data support layer,business support layer,intelligent application layer and user interaction layer are also proposed.Lastly,the main technical features of intelligent operation and maintenance of the HZMB.The intelligent operation and maintenance of the HZMB can provide important reference for the operation and maintenance of other cross-sea transportation infrastructure.
