Análise de um solo colapsível e a sua relação com as patologias em fundações na região noroeste do Paraná

Abstract

The municipality of Maringá is located in the Third Paranaense Plateau, a region of pedogenic geological composition of surface soils, an area characterized by soil collapsivity. The municipality presented during decades a great population growth, that caused the same growth in the small and medium-sized constructions. In which constructive methods were used based only on the experience of the old constructors, without scientific character. This fact led to the appearance of pathologies, such as fissures, cracks and disruptions caused by differential repression of foundations, which suggests with a possible area of collapsible soil. These pathologies were cataloged in a Polygonal Map of Reimbursement by rupture of the water supply piping of the municipality, from this map were collected two indeformable samples for analysis in the laboratory, the first sample is of an area that presents problems with the pipe rupture And the other sample was taken from a new housing site in the municipality. With the analysis of the samples it was possible to verify the influence of the soil collapsivity in the areas of reimbursement by rupture of the supply pipe; With the comparison between the two samples, a possible area susceptible to collapse was verified. In addition, with the obtained results it was possible to obtain parameters for the elaboration of foundation projects that support the collapse of the soil, thus enabling the reduction of pathologies caused by this soil characteristic of the municipality.
