Análise dos métodos semiempíricos na previsão de uma prova de carga estática (PCE)

Abstract

This article presents an analysis of the results obtained from a Static Load Test (SLT) performed on a continuous flight auger (CFA) pile, in comparison with semi-empirical methods found in Brazilian literature, such as Aoki-Velloso, Laprovitera, Monteiro, Décourt-Quaresma, Antunes-Cabral and Teixeira. Settlement was evaluated using the Poulos and Davis method, with different k coefficients used to estimate the modulus of elasticity based on the Standard Penetration Test (SPT), in order to determine which value is most suitable for settlement estimation when compared with the test results. The semi-empirical method of Antunes and Cabral, using minimum parameters, was the one that most closely matched the maximum load applied in the pile test, whereas the Aoki-Velloso and Décourt-Quaresma methods were more accurate for the ultimate load obtained by extrapolation of the load-settlement curve.
