Análise geotécnica no núcleo Nova Marabá baseada em relatórios de sondagem, Marabá- Pará

Abstract

Civil construction depends heavily on the knowledge of the physical and mechanical properties of the soil and, to this end, has tools that enable its characterization. The present study aims to guide this knowledge in a previously established area, through reports provided by companies operating in the city of Marabá-Pa. For this purpose, a study area was divided into 05 zones, distributed in the Nova Marabá neighborhood, aiming to facilitate the preparation of the geotechnical mapping based on the standard and mixed penetration test (SPT). This characterization considers the type, profile, geotechnical characteristics and resistance to penetration (Nspt) of the soil. From the analysis of the reports, a map of zones of risk of repression was generated, which showed that the soil properties can vary significantly in nearby areas and not always the smallest resistances occur at the edges of watercourses.
