Abstract

The Tschebotarioff Effect in precast piles driven into soft soil is responsible for causing deformations and displacements in these. In this way, seeking to analyze the behavior of precast piles, a theoretical dimensioning of this effect was elaborated, from the Tschebotarioff method, applied to precast piles of different sections: 18x18cm, 23x23cm and 30x30cm, with vertical loads of: 300kN , 500kN and 900kN respectively, assuming their driving in a real soil profile, in the region of Florianópolis/SC. Then, the behavior between the three piles was compared and the consequences that the effect can have on the foundation structure were compared, such as the horizontal displacement (measured using the Ftool tool), or the consequences on the superstructure, supported by the foundation, which may lead to the collapse of the building. As a result, it was observed that piles with larger sections suffer less deformation by the Tschebotarioff Effect than piles with smaller sections.
