NIETO LEAL, Andrés  and  KALIAKIN, Victor N. GENERAL RESPONSE OBSERVED IN CYCLICALLY LOADED COHESIVE SOILS. Cienc. Ing. Neogranad. [online]. 2016, vol.26, n.1, pp.21-39. ISSN 0124-8170.  https://doi.org/10.18359/rcin.1673.

The response of cohesive soils subjected to cyclic loading is affected by different factors; the most important are soil type, stress or consolidation history, and specific test conditions. To better understand the behavior of cohesive soils subjected to cyclic loading, beginning in early 1960's, a rather substantial body of experimental work has been performed. This has involved different types of soils, tested at different values of overconsolidation ratio, and subjected to different cyclic loading histories. This paper compiles the most important findings of the aforementioned experimental work on cohesive soils. It summarizes the general behavioral trends observed for cyclically loaded cohesive soils. Besides, several key characteristics of cyclically loaded cohesive soils that any rational mathematical simulation must account for have been identified, thus offering the general trends that should be taken into account in the development of new constitutive models used in predicting the response of such soils.

Keywords : Cohesive soils; cyclic loading; post-cyclic response.
