Through studies on the choice of type of foundation to use a certain work, always when the foundation is to pile it is necessary to build another structural element, the block of crowing or also called pile caps. Several studies have been made taking into account the block on stilts without the influence of soil. So this work demonstrates the relationship of methods of calculation of reactions in piles and tensions in chunks of some authors that take into account the influence of soil or not, with the numerical analysis. To analyzethe fundations the program DIANA was used in conjunction with MIDAS / FX +. With these results, ground-structure in the study of these blocks can be concluded on the importance of the interaction, being distinguished that as example, that if the ground are taken in consideration in the analyses of rigid blocks, the biggest reactions if are concentrate near the corners of the block, independent of the type of load application studied and not in the props central offices as some simplified methods consider. This leads to a closer examination of reality and therefore more accurate.
