Abstract

The present paper puts forward the object of studies on signals of dynamic test about piles with wavelet analysis. The traditional testing data of stress wave reflection is exploited. More available information, which expresses the propagating process of stress wave in piles, is obtained by getting ride of errors from actual measured signals. The conduction results, with some examples shown, demonstrate that this method can get more accuracy and flexibility.

Key words

Pile testing / integrity / stress wave / wavelet analysis / fault diagnosis
