Abstract

The transient-state flexural waves impulse response tests are alternatively introduced to the integrity evaluation of piles where the tops are inaccessible for conventional longitudinal wave testing. The conventional constant velocity-based one-dimensional wave theory is no longer suitable to interpret such testing results. In this research, linking the guided wave theory and resonance concept is a simple and efficient method to describe the dispersive wave velocity and precisely evaluate the on-site length of pile bents supporting a rail viaduct in central Taiwan.
