Probabilistic Analysis of Bearing Capacity of Continuous Flight Auger Piles
Abstract
The present paper verifies the application of semi-empirical methods to compute the bearing capacity of continuous flight auger piles built in Goiânia-GO, considering a probabilistic approach. The semi-empirical methods proposed by Aoki and Velloso (1975), Décourt and Quaresma (1978) and Antunes and Cabral (1996) were used together with the Monte Carlo method (METROPOLIS; ULAM, 1949) in a probabilistic approach. Soil variability was considered through the results of standard penetration tests. The results were compared with static pile load tests performed in situ, which allowed probabilistic analysis of failure for each semi-empirical method assessed. Among those analyzed, the Décourt and Quaresma (1978) method presented a probability distribution closer to the one computed using the pile load tests data, which indicate this method as the most appropriate for the geotechnical design of continuous flight auger piles under local conditions.
