Obtenção do ângulo de atrito interno e coesão do solo a partir de sondagens SPT realizadas na UTFPR - Campus Pato Branco - PR

Abstract

The search for knowledge of variables that have influence on the soil behavior can contribute to avoid disasters inside civil engineering. Physical index data such as soil cohesion and internal friction angle are very important to help understand the soil behavior when under charge. There are different methods to obtain theses data and one of the most spread is the direct shear test in laboratory. Other method to obtain these values for internal friction angle and cohesion it is given by calculation based on data from the Standart Penetration Test (SPT). The present research had as a goal to analyse the relation between data from Standart Penetration Tests, executed at UTFPR - Campus Pato Branco to the construction of new buildings for the university along with data acquired from the direct shear test of intact specimens. The specimens were taken from places near the point of where the probing was made, to try and guarantee that the soil being analysed was similar, and in that way the comparison between data would be more reliable. The values obtained with the direct shear test turn out to be unusable to the goal of this research seeing that these values were to distinct from the expected and from values obtained by other authors in nearby regions from this research
