In the present investigation, representative parameters that influence the shear strength of a granular soil were studied. The objective of this study is to verify that the friction angle of a granular soil can be obtained through a linear expression of three variables, and by using the homothetic curve method. There are many variables that influence the shear strength of a granular soil. However, in this investigation only the variables of dilatancy and the friction angle are considered, this due to the delimitation of variables and parameters developed in the study, which could be considered for future investigation and to obtain an expression with a greater number of parameters of influence in the shear strength. The shear strength of granular soils depends to a great extent on the friction angle and the dilatancy. In this way, an experimental study was realized in sand samples in order to obtain an expression that allows correlating the friction angles of samples with original granulometry and samples made with homothetic curves criterion. Then, maximum and minimum density tests and direct shear tests were realized, where specimens compacted at 70% relative density were tested. Finally, an expression based on the angle of friction and the dilatancy was obtained, with a coefficient of determination of the equation close to unity, which shows a clear fit of the expression.
