Propriedades geotécnicas de um solo residual de basalto na região de Guarapuava - PR

Abstract

Soil is a variable, heterogeneous, anisotropic material, susceptible to weather and decomposition processes. An in-depth study of the geotechnical characteristics of a given soil, allows measuring these spatial variability and, if correctly interpreted and used in Engineering projects, guarantee greater reliability to the adopted solutions. For this reason, this work studies the region of Guarapuava, a municipality inserted in the third plateau of Paraná, where basaltic formation is predominant. The literature on the geotechnical characterization of the region is scarce and the research of this work is a precursor in the collection of data with a view to enriching the technical knowledge of the parameters of the typical soil of the region. In this context, this work characterizes the residual basalt soil, in the Guarapuava region, and compares its behavior with similar soils from other regions, contributing to future research involving the geotechnical data of that soil. The research has an exploratory character, with comparative analysis of other similar works. It addresses the elementary study of the geology of the region, as well as the formation processes of residual basalt soil. A database, with experimental results found in the literature, for similar soils, is built. Deformed and deformed samples were collected and subjected to laboratory tests of granulometry and soil consistency limits. The tests were carried out in the Soil Mechanics laboratory of UTFPR, Guarapuava campus.
