Caracterización del grado de dispersión en arcillas de la zona Nor-Oeste de la Cuenca Sedimentaria de Loja, para determinar potencial generación de procesos de piping

Abstract

Abstract: The study and identification of dispersive clays is of great importance since they are closely related to geological risks due to their instability in the presence of a hydraulic flow due to which they can generate tunnel-type structures or also known as piping which weaken the normal structure of the soil making it unusable for construction or agricultural activities. The present work details the quantitative and qualitative analysis of the dispersion degree of clays present in the Northwest zone of the city of Loja through the use of Crumb (ASTM D 6572-12) and Double Hydrometer (ASTM D 4221-99) tests where considerable dispersion values were obtained in already established neighborhoods and other areas to be taken into account due to the growing peripheral expansion that the city has as a result of the constant population growth, and represent a considerable risk both now and in the future if no action is taken.
