Caracterização geotécnica do solo do campo experimental da Universidade Federal do Ceará – Campus Crateús

Abstract

This work presents the characterization and classification of the soils, from the accomplishment of tests, of the Experimental Field of the Federal University of Ceará - Campus Crateús. In order to obtain knowledge of the soil under study, a geotechnical study is carried out, which includes the execution of laboratory tests. In all works, it is necessary to predict the behavior of the soil, considering that the quality of engineering works depends on the knowledge of the conditions of the subsoil, being indispensable for safe and economical projects, with the objective of contributing to its use as a building material and in paving (base and/or sub-base layers). The work methodology consists of carrying out geotechnical characterization tests to determine the material's characteristics in terms of granulometry, consistency and compaction tests to discuss its use as a landfill and paving material. Based on the analysis of the parameters obtained in the tests, it can be seen that the analyzed subsoil presents poorly graded granulometry and non-plastic characteristics. After obtaining the results of the laboratory tests, the soils were classified, according to the Soil Classification System (SUCS), according to their granulometry, as well-graded silty sand. Finally, with the completion of this work, it was possible to provide data regarding the geotechnical properties of the subsoil, for future research that is carried out in the experimental field under study.
