Correlación del módulo de elasticidad obtenido con el ensayo triaxial UU y los datos del ensayo de corte directo UU en la Cangahua de la ciudad de Quito

Abstract

The investigation was made with the objective to find an equation that correlates the modulus of elasticity of the soil from direct shear UU and classification SUCS data with the triaxial test UU. Traditionally, the modulus of elasticity of the soil can be determined from the simple compression test or triaxial test data through the slope of the curve deflecting stress vs. vertical unit strain. Six unaltered soil blocks were obtained, which correspond to Cangahua of six different places in the north and northeast of the city of Quito. The results of the SUCS soil classification and shear strength tests were studied using an analysis of variance ANOVA to determine the variables statistically representative, which were applied in a multiple linear regression to define the correlated equation. Statistical results were corroborated through the analysis of assumptions of residual values using hypothesis tests for ANOVA models and multiple linear regression. The study was complemented with the analysis of the levels of confidence and difference of means
