Abstract EN
To warn of the stability of retaining wall structures with damage, a simplified mechanical model and a finite element model of this retaining wall-soil coupling system are established.
Via finite element model updating, a baseline finite element model of the wall-soil system is acquired.
A damage alarming index ERSD (Energy Ratio Standard Deviation) is proposed via the wavelet packet analysis of a virtual impulse response function of dynamic responses to this baseline finite element model.
The internal relationships among the alarming index, earth pressure, and damage stability of the wall are analyzed.
Then, a damage stability alarming method for the retaining walls is advanced.
To verify the feasibility and validity of this alarming method, vibration tests on the baseline finite element model of a pile plate retaining wall are performed.
The ERSD is used as an alarm for the damage stability of the wall.
Analysis results show that, with an increase in the ERSD, the stability of the wall changes from a stable state to an unstable one.
The wall reaches a critical stable state when the alarming index reaches its threshold value.
Thus, the damage stability of this pile plate retaining wall can be alarmed via ERSD.
