Long-Term Deformation in Clay

T. H. Wu

The general objective of this research is to investigate the creep properties of clay soils and its relationship to embankment deformation. A preliminary study of this topic was made by Professor W. H. Perloff under contract EES 260. The present project is specifically aimed toward the effect of stress-state on creep behavior. The results obtained during the first year's experiments may be summarized as follows: (a) The stress state has an important influence on creep rate. (b) For an ordinary embankment, the deformation due to creep (no drainage) is of the same order of magnitude as that due to consolidation. (c) A consistent stress-strain-time relationship holds for each of the different stress-states. (BPR abstract)
