- Abstract
Sonoprobe method has been applied in non-destructive inspection of anchorage project. Its fundament is to cause anchor bar's elastic vibration by dynamic transient excitation and the flaws of anchor bar can be estimated or deduced by determining the transient response. The numeric solution!of hyperbolic equation by FEA indicates that the deductions should comply with the acoustic parameters such as sound velocity, vibration range, wave shape etc., when inspecting the interior flaws in grouting of anchor bar. As a non-linear dynamic system,"the artificial neural networks dealing with quality inspection of gray system have been proved efficient.
