RESUMO

There are very common cases of works that have problems due to the collapse of foundations and soil, and in the most of the works, the solution applied is the underpinning with Mega piles of concrete that, despite the wide use, there are few studies on this type of foundation. With the aim of add parameters to the technical means about this type of foundation and the influence of the collapse of the soil in its load capacity, load tests were performed on concrete Mega piles with lengths of 6 and 8 meters, in soil with natural moisture and pre-flooded. With the results it was possible to verify that the decrease in the load capacity in this type of foundations is significant and should be considered when used in collapsible soils
