Análisis y determinación de correlaciones entre la resistencia al corte no drenado de suelos finos y el ensayo spt para la ciudad de Barranquilla

The Standard Penetration Test (SPT) is widely used globally to correlate soil strength and stiffness characteristics. However, existing correlations in the literature between SPT and soil characteristics have been primarily developed for soils with specific characteristics in terms of grain size distribution, plasticity, mineralogy, and formation processes. In the Colombian context, efforts to determine local correlations are limited. Therefore, selecting the appropriate equation to estimate stiffness and shear strength from SPT can be a complex task. In this research, specific correlations were developed between SPT and undrained shear strength of fine soils in the city of Barranquilla, and the Atlántico department. Additionally, it was evaluated how other soil variables could improve the predictive capabilities of these equations. The predictive capability of the pocket penetrometer was also analyzed compared to unconfined compression tests. The results indicate that the proposed equations can reasonably well predict the undrained shear strength of fine soils using SPT and pocket penetrometer data
