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.
