Resumo

This study aims to compare the load capacity of shallow and deep foundations, spread footing and piles, using dynamic penetration resistance values of PANDA 2 test in tropical compacted soil, replacing the parameters obtained by CPT and SPT that implement the traditional methods of capacity of design load. Furthermore, this research includes also the settlements analysis in each of the situations proposed. The comparison of the load capacity of footing and pile with predefined dimensions was made through theoretical and semi-empirical methods. The PANDA 2 results use were satisfactory, with little variability when compared to SPT and CPT use for foundations design in the studied soil. With regard to settlements, as expected, the settlement for pile was relatively lower than the settlements on footing. The main contribution of this paper was the practical application of Panda 2 results use, through methods of estimate foundations load capacity and settlements.
