Real-time Bridge Scour Monitoring System by Using Capacitor Sensor
نویسندگان
چکیده
Scour is the erosion of stream bed or bank material from bridge foundations due to flowing of water. Data logging from sensor and electronic communication systems can monitor scour in real-time to ensure the integrity of bridge structure. A number of parameters are associated with scour, thus different types of sensor are required to measure the individual affecting factor. A simple capacitive type direct scour sensor system is proposed and validated by simulation. The result shows that any change of the river bed dielectric property is a direct indication of scour. Due to simple capacitive structure of the sensor system, it is highly robust and easy to implement. The system can easily be implemented with an existing bridge structure. A wireless telemetry system can be used to send the real-time data from the proposed sensor to a desktop computer at the monitoring lab.

Taiwan is located in the rim of the Pacific Ocean. The activities of the earthquake happen frequently, which threaten the safety of the bridge in the Taiwan Island. Besides, the severe floods resulted from the typhoon or storm events can cause great damages due to the bridge scouring. The steep-sloped rivers and sand mining problems in Taiwan accelerate the degradation of the riverbed. Scouring...
متن کاملWhite Paper: Tiltmeter-Based Bridge Scour Monitoring
Scour is by far the primary cause of bridge failures in the United States. Scour and other hydraulic effects are particularly threatening because the deterioration is often invisible , hidden beneath turbid water. Many scour monitoring methods attempt to measure the development of scour pockets themselves. However, this is difficult due to debris — both floating and submerged — and shifting str...
متن کاملSimple Cost-effective Scour Sensor
Local bridge scour is caused by the interference of bridge piers with the flow of water and is characterized by the formation of scour holes. Local scour occurs at a bridge pier when the local flow field is strong enough to remove bed materials. Several variables affect the scour depth including the flow intensity, the relative flow depth, the pier-width, and the properties of the river bed mat...
