Effect of Stress Release on Shear Modulus of Clays
Publication: Journal of Geotechnical Engineering
Volume 109, Issue 10
Abstract
An experimental study using resonant column tests determined the effect of a temporary release of confining pressure (under conditions of no drainage) on the low‐amplitude shear modulus, of two cohesive soils. The soils tested were a remolded kaolinite clay and a natural “undisturbed” silty clay. It was found that a temporary release of confining pressure induces disturbances which are manifested by a drop in the value of After reapplication of the original confining pressure the cohesive soil regains the lost amount of with the logarithm of “regain‐time” increasing linearly with the logarithm of the duration of the confinement prior to its release (i.e. the “age” of the cohesive soil). It is suggested that the findings be used for estimation of the secondary time that must be taken into account in a resonant column test on “undisturbed” samples, to establish representative of the in‐situ value.
