Post-Cyclic Behaviour of Clayey Soil

The post-cyclic behaviour of a clayey soil after subjecting to cyclic loading is presented in this paper. Tests were carried out on the samples both by allowing the cyclic pore pressure developed during cyclic loading to dissipate and without dissipation. While the samples subjected to post-cyclic monotonic loading without dissipation of cyclic pore pressure exhibited a highly overconsolidated behaviour, the samples after dissipation of cyclic pore pressure exhibited a lightly overconsolidated behaviour. All the samples subjected to cyclic loading exhibited a higher undrained strength during post-cyclic monotonic tests, when compared to the samples without prior cyclic loading history. Post cyclic consolidation tests depicts that the samples show signs of apparent over-consolidation. © 2013 Indian Geotechnical Society.
