Análisis del comportamiento de los suelos limosos frente al sometimiento de carga en ensayos de compresión triaxial CU y UU.

Abstract

In the present work the statistical analysis was performed between parameters of shear strength under total conditions versus parameters under effective conditions. For this purpose, the triaxial tests UU and CU were used. It is common knowledge that this type of essays are widely disseminated and therefore the knowledge of the variability in the results that they present, allow engineers and students the correct application of these essays in different projects. Regarding the methodology, the choice of a slope of the locality made up of 4 soil strata with the following classification: SP, SM-SC, MH and CH. Then with the extraction and the preparation of specimens the mechanical parameters of each stratum were obtained through triaxials UU and CU. From these results the comparison between failure envelopes was made and the respective correlation was obtained. The results obtained for the tested soils show that in the triaxial UU test both the friction angle and the cohesion values are lower than those obtained in the triaxial CU test.
