Avaliação de métodos semiempíricos para capacidade de carga de estacas hélice-contínua em Goiânia-GO

Abstract

The continuous flight auger (CFA) pile foundation is a widely practiced solution in Goiânia for large-scale buildings. The calculations are performed using semi-empirical methods, which correlate the stresses supported by the soil based on the Standard Penetration Test (SPT). This study seeks to evaluate the settlement and the semi-empirical methods in comparison to the result of a Static Load Test (SLT). The Antunes and Cabral (1996) method, with minimum parameters, yielded the closest result to the value determined by the test, just as the Laprovitera and Benegas method also achieved a close result. However, all methods had predictions above the test's failure load, which is contrary to safety. Therefore, it highlights the importance of field testing to ensure the safety and optimize the geotechnical engineering design.
