Abstract

in this article is analyzed and discussed the information from a survey made to a group of Civil engineering postgraduate students about how the concept of security factor is interpreted and employed in geotechnical structures design. The obtained results contribute to the understanding of variables related to the calculation of a security factor, seen as an exercise that transcends the use of mathematical formulas and involves the engineering judgment, becoming a key aspect at the moment of its application in real contexts.
