Abstract
The influence of the stress anisotropy imposed during consolidation on the stiffness of soft Bangkok clays was explored using the triaxial equipment. Several testing conditions were imposed on the samples to examine the effects of stress state as well as the rate of loading. It was found the stiffness at moderate strain levels was almost independent to the stress state; i.e., the deviator stress level. On the contrary, the rate of stress application played a very important role. The faster the rate of stress application, the higher the values of the stiffness at moderate strains. Nevertheless, a simple empirical equation can be given based on the test results to represent the influence of rate of application on the stiffness of soft clay.
