ABSTRACT
It is well known that there are two types of time-dependent behavior for soil. One is consolidation and the other is brought about by the inherent viscous nature of the soil skeleton. The interaction between the pore water and the soil skeleton results in consolidation. The viscous properties of the soil skeleton are related to the microstructure of the soil particles. Although many problems due to the consolidation of various types of soil have been solved, some problems still exist. One of them is the interaction between the viscosity and the changes in the soil structure. In the following, two problems will be discussed. One is the in“uence of the soil specimen thickness on consolidation and the other is the interaction between the viscoplastic properties and the strain softening due to structural changes.
