Abstract

The materials available in nature as soils are widely used by man , however, in a disorderly manner can cause trouble for himself . In civil engineering the concept that serves of soils is a cluster of rocks already decomposed, which can be undone with the use of excavation. The soil as constituent material of construction is of great importance, such as concrete and steel. The nature does not provide materials that are able to meet the ideal conditions for the settlement of foundations, for example, a good bearing capacity with low deformability The techniques employed in engineering of foundations in our time is best suited for use as a base of support on the ground. Thus, this study tackles the mapping of soils in the State of Rio Grande do Sul, with the lifting of the main geotechnical parameters already studied. The information was organized by physiographic regions distinct as Peripheral Depression, shield-South-riograndense, plateau and coastal plain, in a way that is better understanding, as some authors claim that the regions can be classified by various characteristics. This demarcation covering all localities of Rio Grande do Sul State makes it possible to analyze both the geotechnical characteristics, such as estimating the values closest to the points analyzed. This study was prepared a database supported by ArcGIS, Geographic Information System (GIS), which presents itself as a very viable tool on inserting information in its database, relating to points at coordinates, in the case of this research, with the map of the State. The results were distinguished with statistical data on "graphical analysis" and mapping of regions, styling himself "mapping ". Us results "mapping", was in need of a division of physiographic regions, for which the ArcGIS can present with better reliability the interpolations in the generation of thematic maps. This research was conducted in order to analyze and compare the parameters showing similarity in the State of Rio Grande do Sul and to contribute to the engineering professionals in the elaborations and project studies.
