In the slope stability deepening seminar project, different stability methods supported by spreadsheets were analyzed and compared through the equations of voussoirs developed by Fellenius, Bishop Simplified, Janbu Simplified, Hoek and Bray abacuses and Janbu abacuses, determining the safety factor of a slope located in the municipality of Ibagué; for this it was necessary the application of qualitative and quantitative analysis of the slope located in the department of Tolima, more exactly between the coordinates North 982.500 and East 870.100, between elevations 1222.75 and 1237 m.a.s.l., A comparative analysis was also carried out with the degree work done by Leidy Yhoana Ardila Rodríguez entitled "Analysis of slope stability of the slope located in the Eduardo Santos Cra 1ª. Sur Ibagué Tolima" (Ardila R., 2020).
