Remote Vibration Based Monitoring of Bridge Scouring

Engineering Technology Center, Room Q109

Abstract

The gradual erosion of the sediment around a bridge foundation is called Scouring. This erosion is caused by water flow and increases during times of high-water flow such as flooding. The scouring leaves the bridges structurally unsound over time and jeopardizes the safety of the structure. Approximately 60 percent of bridge failures in the United States are caused by scouring. A variety of types of devices have been used to detect scouring. Most of these devices only observe the scouring and not the structural integrity of the bridge. The typical approach has relied on visual inspections of the bridges after flooding. This approach provides an incorrect estimate of pre-existing scour and its effects on the bridge foundation as well as a posing a safety concern to the inspection crew due to the bridge’s integrity. The goal of this research is to development, test and field implement a new type of vibration-based sonar sensor system that will not only detect scouring but will observe the bridge’s health during flooding events. This system will provide remote data monitoring capabilities which will help inspectors assist with making time crucial maintenance decisions.
