Aplicação de ferramenta SIG para a interpolação de dados obtidos em ensaios SPT: análise da profundidade do lençol freático, do impenetrável e dos valores de Nspt da região central de Macapá-AP

Abstract

With the rapid advancement of civil construction in the city of Macapá, especially with regard to the verticalization of the city, it would be indispensable, as a form of urban planning, the survey of geotechnical information to enable the creation of maps that will support faster interpretations of the parameters. of interest to the building industry. In this work, 36 Standard Penetration Test (SPT) drillholes were used, which were within the study area, in order to obtain soil information that allows the creation of maps that allow the visualization of the groundwater depth in plan, the impenetrable percussion level and the NSPT values. For this, the Geographic Information System (GIS) becomes indispensable for the creation of maps, since it is through GIS that the computational treatment of geographic data is performed. In the development of the maps, a database was created with information taken from the drill profiles, and the geographic coordinates of each hole were sought through auxiliary tools. The database was launched in ArcMap 10.3 software and through it, ordinary kriging interpolation of the soil attributes was applied to create the surfaces present in the maps.
