• Abstract:
  The research performed in this project focuses on the application of instruments including accelerometers ; and tiltmeters to monitor bridge scour. First, two large scale laboratory experiments were performed. One ; experiment is the simulation of a bridge with a shallow foundation, and the other is the simulation of a bridge ; with a deep foundation. A series of instruments were installed on the simulated bridge to monitor the ; performance of the bridge due to scour. Both the shallow foundation experiment and deep foundation ; experiment show that accelerometers and tiltmeters can be used in scour monitoring events since both give ; warning of bridge failure successfully. Subsequently, two individual monitoring systems were designed and ; installed on two bridges: US59 over Guadalupe River Bridge and SH80 over San Antonio River Bridge in ; Texas. Realtime data are collected and transmitted to a computer server at Texas A&M University, which ; can be accessed remotely. The instrumentation on the two bridges does not show great hope of application ; of accelerometers to monitor bridge scour because of a lack of sufficient excitation from traffic. Another ; issue with the accelerometers is the high power consumption during the transmission of accelerometer data, ; which cannot be satisfied with a typical solar panel and battery. Tiltmeters can provide the integral behavior ; of the bridge, and therefore are very useful devices for scour monitoring. Guidelines and protocols for scour ; monitoring based on the US59 over Guadalupe River Bridge and the SH80 over San Antonio River Bridge ; are provided in the study.
