الملخص EN

To eliminate the influence of excitation on the wavelet packet frequency band energy spectrum (ES), ES is acquired via wavelet packet decomposition of a virtual impulse response function.

Based on ES, a character frequency band vector spectrum and damage eigenvector spectrum (DES) are created.

Additionally, two damage identification indexes, the energy ratio standard deviation and energy ratio variation coefficient, are proposed.

Based on the damage index, an updated damage identification method for retaining wall structures is advanced.

The damage state of a retaining wall can be diagnosed through DES, the damage location can be detected through the damage index trend surface, and the damage intensity can be identified by establishing a quantitative relationship between the damage intensity and damage index.

To verify the feasibility and validity of this damage identification method, a vibration test on a pile plate retaining wall is performed.

Test results demonstrate that it can distinguish whether the retaining wall is damaged, and the location of partial damage within the retaining wall can be easily detected; in addition, the damage intensity of the wall can also be identified validly.

Consequently, this damage identification theory and method may be used to identify damage within retaining wall structures.
