Zusammenfassung:The process of precipitated variation of a soil volume when subjected to increase in stresses which withstand and/or the degree of saturation, it's also known as collapse. Collapse Potential of soils can be determined from correlations derivative of the material properties index. That's why in this work, it was evaluated using different methods the Collapse Potential of soils for ten specimens of tropical residual soils coming from five different points in Aburrá and San Nicolás Valleys, and the results were compared with the index collapse obtained using the duple-oedometer test. It was achieved to establish which of the procedures is closer to the traditional test results, and thereby obtain an approximation to the potential collapse using easy implementation methodologies with significant costs savings and rehearsal times, without loss of reliability evaluation. / El proceso de variacin precipitada del volumen de un suelo cuando se ve sometido a un aumento en las tensiones que soporta y/o cuando se satura, se conoce como colapso. El potencial de colapso de los suelos se puede determinar a partir de correlaciones derivadas de las propiedades ndice de los materiales. Se evalu por diferentes mtodos el potencial de colapso en diez muestras de suelos residuales tropicales provenientes de cinco puntos diferentes de los valles de Aburr y San Nicols, y se compararon los resultados con el ndice de colapso obtenido a partir del ensayo de doble edmetro, logrando establecer cul de los procedimientos se acerca ms a los resultados del ensayo tradicional y de esta manera obtener una aproximacin al potencial de colapso a partir de metodologas de fcil ejecucin con ahorros significativos en tiempos de ensayo y costos asociados, sin prdida de confiabilidad en la evaluacin.
