Digital Twin‒based Long-span Bridge Health Monitoring

Project Reference PSRI/68/2306/RA
Project Title

Digital Twin‒based Long-span Bridge Health Monitoring

Applicant The Hong Kong Polytechnic University
Contact Professor Yong XIA
Project Duration 24 months
Approved Funding HK$ 13,404,400.00
Project Summary

The proposed project aims to develop a digital twin‒based long-span bridge health monitoring platform.  The Tsing Ma Bridge will be used as the testbed of the project for developing automatic traffic monitoring system, realistic bridge fatigue damage assessment and prediction system, vehicle-barrier collision monitoring system and vehicle safety assessment system in high winds. Sensors on the bridges, cutting-edge artificial intelligence (AI) techniques, finite element analysis, and Bridge Information Modelling (BIM) will be integrated into the monitoring platform to enhance the efficiency of the road network and road space, as well as improve driving safety.
