Estruturação preliminar de banco de dados georreferenciado de sondagens à percussão e mistas em Fortaleza - CE

Abstract

The present work is the result of the collection and organization of a georeferenced database of preliminary geotechnical investigations, through field tests: Standard Penetration Test (SPT), rotary drilling and mixed drilling; carried out in the municipality of Fortaleza - CE, which has an area of approximately 312 km². Furthermore, as an example, standardized survey bulletins were prepared in the Guararapes neighborhood. Currently, there is a problem involving the lack of systematically gathered geotechnical information on the soil of Fortaleza, which would assist future preliminary studies; however, without the intention of dispensing with the need for specific investigations on each plot of land to be built. From this perspective, the objective is to structure a georeferenced database of surveys carried out in the city of Fortaleza – CE, with the ability to be digitally shareable. Through a methodology based on data collection and the implementation of a Geographic Information System (GIS) environment, applied to 751 selected drilling holes. In this way, Google Earth Online tools were used to spatially distribute the holes; later, with the QGIS 3.28.11 program, geoprocessing and cartographic production were carried out. Furthermore, the Google My Maps platform was chosen to receive the processed data, as it is free and easy to edit, with uniform bulletins being shared via a Google Drive link. Therefore, this work provides a georeferenced survey database, with both academic relevance to support future research and practical relevance in society. Finally, it is hoped that this work can contribute in the future to the preparation of geotechnical mapping of Fortaleza, with the purpose of guiding the planning of works and projects in the capital of Ceará.
