Previsão da capacidade de carga de estacas pré-moldadas de concreto através de métodos semiempíricos na cidade de Nobres/MT.

Abstract

This work presents the geologic description and geotechnical investigations of soil at site of driven down concrete pre-cast piles. It describes the piles driving down and estimate the ultimate load through out semi-empirical methods, and dynamic formulas comparing them to values obtained from interpretation of slow load bearing tests. It also shows in appendix, an application of the mathematical model of Massad (1993). The piles were pushed down, by hammering, on the foundations of a construction at municipality of Nobres, MT. The local soil is formed by sand layers, with different percentages of fines. The comparison of the results, leads to conclude that the value of ultimate load, measured throughout load bearing tests, agrees with that estimated by semi-empirical methods, and the that application of dynamic formulas can be done with adjustment on safety factors.
