The Degradation of Saturated Clay’s Un-Drained Shearing Deformation Modulus under Cyclic Loading

Abstract:

The un-drained shearing deformation modulus of clay will degenerate under cyclic loading. This degeneration is attributed to two reasons, the first one is the reduction of effective pressure due to the increment of super pore pressure; another one is the change of soil’s structure due to the accumulation of plastic shearing strain. Firstly, based on the result of un-drained shearing tests, two formulations were obtained which include initial deformation modulus ratio versus over-consolidated ratio and initial deformation modulus ratio versus initial shearing strain. Then, the quasi-over-consolidated ratio was introduced to consider the effect of super pore pressure, and a fitting formulation was applied to consider the influence of shearing strain. At last, the degenerate formulation of saturated clay’s deformation modulus was deduced, which was proved reasonably by the test results.
