ANÁLISE DE SOLO POR MEIO DE SONDAGEM SPT: estudo de caso de uma residência de dois pavimentos em ambiente urbano

Abstract

The synergy between theory and practice bring procedures that should always go together, based on this, a work was proposed with the objective of presenting the characterizations and methods for the use of simple recognition percussion soundings, demonstrating its service methodology for a good execution at the construction site. For this purpose, a percussion drilling of the SPT test (Standard Penetration Test) was carried out, its execution cycle, water level verification, soil sample collection of SPT drilling errors, analysis and verification of the results of the individual SPT survey profile. Having discerned these indicators, two SPT holes were used in the area to be built in the municipality of the Três Pontas MG, concluding which method is more effective and safer for the dimensioning of the foundation project, where the block model was used of foundation with four drills, where the block model was descend to the impenetrable with a depth of 8.15 meters and 9,15 m. All the interpretation of the results obtained by the SPT survey enabled the responsible designer of the fondation to make a better choice to adapt to the subsoil, according to the characteristics found in his profile.
