Project summary
Recently, with the increasing global demand for mass transportation and freight, the maintenance of existing transport infrastructure has become important. Therefore, it is essential that railway infrastructure is reliable, cost-efficient, and provides a sustainable transportation mode. However, most of our existing railway infrastructure is ageing and requires continuous monitoring to keep them in service, which requires significant cost. Moreover, these structures are subjected to heavier axle loads, faster train speeds, and greater frequencies of trains, which have resulted in rapid deterioration over time. Apart from that, factors such as extreme variations in temperature, heavy rainfall and increased frequency of flood events due to climate change have introduced increased uncertainty in the long-term performance of such infrastructure assets. Hence, efficient and reliable infrastructure inspection and monitoring are needed to ensure these systems run smoothly at a reasonable cost.
This PhD aims to develop a framework for digital twinning (DT) of railway bridges and provide informed decisions for their repair and maintenance schemes. DT can be imagined here as a digital representation of a physical asset (i.e., a railway bridge) which serves as a ‘living’ digital simulation model and is enabled by the abundance of data (e.g., operational data acquired from the bridge) and advanced data processing and interpretation routines.
The proposed aim will be achieved using the following objectives:
