AI Technical Summary
Existing bridge health monitoring methods lack the identification of pile foundation scour dynamic characteristics under environmental excitation conditions and the optimization of sensor layout, resulting in low measurement accuracy and high cost. The number and location of sensors depend on human experience and are prone to redundancy.
The sensor placement method based on the scour-sensitive mode set is to establish a three-dimensional finite element structural dynamic model, screen scour-sensitive modes, optimize sensor positions and quantities, construct a composite scour sensitivity index, and combine the Grey Wolf optimization algorithm to optimize the sensor layout scheme.
It achieves high-precision identification of scour dynamics in beam bridges under limited sensor conditions, improves the reliability and accuracy of monitoring, avoids the shortcomings of relying on experience in traditional methods, and enables lightweight sensor deployment.
