Zoneamento da resistência à penetração (Nspt) em solos na região na cidade de Fortaleza/CE

Abstract

Fortaleza, as others big centers, have been suffering constantly the reflections of economic and population growth, in which causes the verticalization of the city, as well as road structures adequacy like bridge, overpass, metro and tunnel buildings, turning necessary the increase of soil use and occupation study, mostly through the knowledge of its pedological and geotechnical attributes, obtained from percussive drilling, complemented by rotary drilling. This paper makes a study using obtained data from drillings in a delimited arca, northeast from Fortaleza, generating data about the underground, such as the penetration resistance indicator (Nspt), the hydraulic cargo and cargo capacity. These data received statistical training and created zoning maps, using the ordinary kriging.
