Utilização da compactação para redução do potencial de colapso / expansão de um solo silto argiloso de Massapê da cidade de Icó - CE

Abstract

FIn this paper we present a study of the behavior of a clayey silt soil, the city massapê Icó-CE, which will be used to support the foundations of the structures of a housing development. The objective is to ascertain the efficiency of the technique of compression in reducing the potential for collapse / expansion of the studied soil. A characterization of the ground by means of laboratory tests (grain size, liquid limit, plastic limit, real density, compaction and CBR) and field (SPT). In addition, there were special tests of simple and double edometer type. Were also collected, in one place, a total of 20 percussion boreholes (SPT) and were performed at the study site company. By analyzing the results we observed that compaction proved to be an efficient technique to reduce or even reduce the potential for expansion / collapse of the studied soil. This work contributes to the field of knowledge as proof, from the study of a real case that the compression of potentially collapsible or expansive soils, in fact, reduces its potential to acceptable levels for use as support shallow foundations of buildings.
