The study of anisotropic behavior of soils has been widely addressed in various investigations. Results of the analysis of the mechanical behavior of soils have shown a different response depending on the anisotropy inherent in the formation of the direction of the stress application. The existence of specific laboratory apparatus for the evaluation of anisotropy such as the true triaxial or hollow cylinder have allowed significant advances in the development of models to predict the behavior of soils. In this research the anisotropy of clayey silt soils of the City of Torreón Coahuila it is evaluated, and its hydro-mechanical behavior is studied using conventional triaxial equipment and oedometer device in undisturbed samples varying the direction of soil extraction (0°, 45° and 90°). Preliminary results show differences in the stress-strain response of soils depending on the direction of application of stresses.
