Effect of Creep on Shear Modulus of Clays
Publication: Journal of Geotechnical Engineering
Volume 109, Issue 10
Abstract
An experimental study using resonant column tests determined the effects of drained shearing creep on the low‐amplitude shear modulus, of three cohesive soils. The soils tested were a remolded kaolinite clay, a slurry consolidated clay and a natural “undisturbed” silty clay. It was found that in normally consolidated clays during the first stages of creep, characterized by fast rates of deformation, the value of is reduced significantly. The reduction was more pronounced for the higher stress levels. For the low rates of deformation characterizing the later stages of creep not only regains the initial loss but eventually exceeds the pre‐creep value. In over consolidated clays the initial drop of is not recovered although the value of is increasing slowly with time. It was also found that a temporary release of the confining pressure from a clay specimen may enhance the effects of previous creep on this specimen.
