Evaluación de la licuación y determinación de daños post-licuación en terraaplenes de una vía estatal del austro ecuatoriano : evaluación de los efectos de la licuación en la estabilidad de terraplenes.

Abstract

Ecuador, being a country located in a high seismic risk zone, represents a threat to both the population and civil works structures. The present work is based on the need to analyze the susceptibility to soil liquefaction and the problems related to embankment stability of the Acceso Sur Cuenca project, for which a methodology that includes field work, laboratory tests and data processing was used. We worked with soil samples for 12 points located along the project, which were analyzed by the method proposed by Youd (2001). The results obtained were compared with those obtained by the method of Idriss and Boulanger (2014) and then the stability of embankments was evaluated for different heights. The results show that out of the 12 points studied, 5 are susceptible to liquefaction; however, the embankments located at these points do not show significant displacements.
