dc.description.abstractEl control del potencial de colapso, inducido por humedecimiento, en suelos compactados, es primordial para evitar la formación de grietas y fallas dentro los rellenos que podrían derivar en el daño de las estructuras. Se realizó una investigación de tipo experimental que evaluó el potencial de cambio volumétrico por inundación de mezclas compactadas de arena y caolín bajo dos niveles de esfuerzo vertical constante. Se encontró que las mezclas compactadas a pesos unitarios secos cercanos al máximo de la compactación normal y esfuerzos verticales de 47 kPa y 86 kPa presentaron un comportamiento volumétricamente estable, mientras que mezclas compactadas a pesos unitarios secos por debajo de 16 kN/m3 y contenidos de agua menores al óptimo, desarrollaron porcentajes de colapso hasta de 12%. Durante la investigación, se desarrolló y construyó un equipo de consolidación con control de succión que permite la medición de esfuerzos radiales y el control de la succión. Lo anterior permitió estudiar la influencia de trayectorias de humedecimiento y secado en el potencial de colapso de una mezcla de arena y caolín. Para dicha mezcla se halló que el cambio volumétrico es estable una vez se desarrolló la trayectoria de humedecimiento. (Texto tomado de la fuente)spa
dc.description.abstractThe control of wetting-induced collapse potential in compacted soils is essential to prevent the formation of cracks and faults within the fills that may later result in damage to the engineering structures. An experimental research was conducted to study the volumetric change potential of compacted mixtures of sand and kaolin by flooding the samples under two levels of constant vertical stress. Mixtures compacted at dry unit weights close to the maximum of normal compaction and vertical forces of 47 kPa and 86 kPa were found to have volumetrically stable behaviour, while mixtures compacted at dry unit weights below 16 kN/m3 and water contents below optimal, developed collapse percentages up to 12%. During the research, a suction-controlled equipment was developed and built that allows the measurement of radial stress and the control of suction, which allowed us to study the influence of wetting and drying paths on the collapse potential of a mixture of sand and kaolin. For this mixture, it was found that the volumetric change is stable once the wetting path was developed.eng
