Análise comparativa entre modelos de previsão de recalques com base em sondagens SPT para fundações superficiais e o software Geostudio

Abstract

The soil displacement is an important object of study in the field of geotechnics, and its estimation is essential when it comes to the design of foundation elements. The settlements must obey tolerable limits to guarantee the safety and functionality of the building. In this sense, load test tests are quite effective in obtaining the load-repression behavior, although other means must also be considered, such as SPT surveys, since in addition to setting up a simple test it is also economical. Therefore, this work aims to evaluate the prediction of repression obtained through semi-empirical models and the Theory of Elasticity from the pre-dimensioning of an isolated rectangular shoe based on sandy soils subjected to a 350 kN load and to match the values to those obtained in the GeoStudio software. The procedure was based on the evaluation of the models, with the Schultze and Sherif (1973) model being the closest to the repression of GeoStudio, while the Burland, Broms and Mello (1977) model obtained unfavorable results in all analyzes presented.
