Avaliação da sondagem SPT via estudo de caso

Abstract

The update of ABNT NBR 6484:2020, introduced some changes in the SPT test, such as in the casing tubes, hole location and test stopping criteria. In this way, ABNT NBR 6484:2020 meets the changes that have emphasized safety, quality and environmental sustainability, imposing a continuity on its studies to civil engineers, as innovations will be more and more constant in the industry. of civil engineering and civil construction. Another relevant point is the obligation determined by item 4.3 of ABNT NBR 6122:2019, which requires at least a preliminary geotechnical investigation campaign, consisting of at least percussion soundings (with SPT), in order to determine the stratigraphy and classification of soils. the water level position and the measure of the NSPT penetration resistance index, according to ABNT NBR 6484:2020. For field work, he points out that the problems found are related to company A in relation to the geotechnical study that did not follow the procedures determined by the new ABNT NBR 6484: 2020, which demonstrates that the civil engineer by omission or lack of knowledge or even due to the time, it failed to follow the imposed norms, that can cause damage to the enterprise.
