Medição de energia no ensaio SPT em solo tropical do campo experimental da EECA/UFG – Goiânia. Revista Eletrônica de Engenharia Civil, Goiânia, v. 14, n. 1, p. 261-278, jan./jun. 2018.

The measurement of the kinetic energy arriving to the rod during the test is an alternative to improve the valor of the test, making possible to compare the results obtained by different equipment and teams. This study has the objective to compare different energy evaluations of the SPT on tropical soils in the experimental field of the Civil Engineering School from the Federal University of Goiás in Goiania, to disseminate this technique, build a database and demonstrate the advantages of its use. For the theoretical-experimental analysis, it was used accelerometers and strain gauges on an instrumented rod using a dynamic wave analyzer which allowed the simultaneous monitoring of each hit and posterior analysis of this data on software for this purpose. The main contribution of this research is to validate the importance of choosing the correct integration interval for the analysis of the data of the kinetic energy transferred to the anvil and that this energy is not affected by the length of the rod nor by the soil resistance under this research conditions. Also, it expects to contribute on a database of the energy measured SPT for local teams and equipment.porAcesso AbertoEnsaios de campoSondagemInvestigação geotécnicaSPTMedição de energiaSite investigationsIn-situ testsGeotechnical investigationMeasurement of energyArtigo10.5216/reec.v14i1.47871
