Banco de dados georeferenciado e carta geotécnica preliminar de fundações da região Centro-Norte de Fortaleza-CE

Abstract

The present work It is the structure of a database information geotechnical geo referenced and the development of a cart the primary foundations of a part of the central region - north of the city of Fortaleza. For this, they collected 395 holes polls percussion in local companies. Each borehole is located spatially using the Google Earth program, f hi chosen to be a software grat uch, small size and easy sharing your files. Posteriorly , subdividing Fortaleza in areas 1 km two and using information of mapping Geotechnical the Metropolitan Region of Fortaleza, Collars done by (1996) were 23 regions considered for analysis and a representative determined for each probe region Through statistical methods. From the three sizes establishment f buildings hi an elaborate prelimi letter nar foundations in scale 1: 25.000 for the portion center - north City d and Fortaleza - EC. The forecast of the type of foundation, surface or deep, depth of laying and permissible rate, type and stake diameter and the approximate length , f Hi realized from empirical and semi - empirical available in literature. They were generated also contour maps of N SPT in three different depths. The research concluded that the syst ema used for geo referencing the data collected proved quite adequate, easy to use, and uses small files. Considering small buildings, concludes - if preliminarily that, almost always, the adoption of shoe based small can depth s. As for medium and large buildings, estimates - is preliminarily lengths vary considerably according to the position of the region.
