Results of some recent sonic integrity testing of piles

摘要

During 2005 sonic integrity testing was carried out on just over 5 000 piles. A brief overview of the results appears below. The theory and the practical application of sonic integrity testing have been comprehensively described by Parrock, Hartley, Naidoo and Green (2004). This article therefore deals only with results obtained on a number of sites, mainly in the Durban area. The piles were installed by ten different piling contractors on 98 different sites. Most of these piles were CFA piles. The results are summarised in table 1.
