This paper aims to show that a probabilistic approach, through reliability calculations, provides a means of assessing the combined effects of uncertainty and allows to distinguish which uncertainty has greater impact on the security of a containment structure. To this end, we developed a case study of a temporary containment structure to two basements where reliability analysis applied by the method proposed by the Army Corps of Engineers (1997). As a result, it was observed that the analyzed structure has a high level of performance by comparing the reliability index values supplied by the U.S. Army Corps of Engineers and Eurocode. It is concluded that the reliability analysis, analyzed by the method proposed by the Army Corps of Engineers (1997), is a simple procedure and that their implementation provides a means of assessing the combined effects of the parameters involved in the calculation of the safety factor, even allowing a view of the influence of each parameter.
