| Summary: | This paper presents the analysis of uplift load tests in three precast-concrete piles carried out in a collapsible sandy soil. The piles had 12 m in length and 0.17 x 0.17 m cross section and used strain gauges, in order to know the load transfer in depth. Three tests were performed in a Slow Maintained Load way and conducted in natural soil moisture. A fourth test was carried out after soaking the soil around the pile head. In the same soil it also was carried out other three load tests
with bored piles (12 m long and 0.20 m in diameter), aiming at to compare the results with the precast-concrete piles. The tests were performed in the experimental research site at the State University of São Paulo (USP). The results obtained were evaluated by analytical and empirical methods. |
