Abstract
During the last two decades, pile dynamic testing has gained widespread acceptance as a useful tool for the control of pile behaviour. This paper covers low-strain tests for integrity assessment by means of two vibration techniques (namely, mechanical admittance and sonic tests), which are herein briefly summarized. A mathematical model is presented and discussed, and the results of mechanical admittance tests performed in two sites are interpreted using this model. A large number of sonic tests have also been performed in two sites in Potenza, where pile construction procedures had been previously surveyed, thus allowing the measurement of pile lengths. which have been subsequently compared with test results. The reliability of low-strain tests for integrity control is eventually discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
