Abstract:

This project explores monitoring railroad bridges using a hybrid sensor that measures acceleration, tilt, and temperature. The objective of the research is to detect scour and changing soil conditions at an early stage before railroad operations are affected. The sensors were installed on six railroad bridges and have been in operation since 2013. An overview of the data is presented including recommendations for continued monitoring. A methodology has been created for how to analyze the data and send alerts if changing conditions are detected. Scour conditions are not known to have occurred on any of the bridges, but the data collected can provide insight into the structural response of bridge piers.
