Abstract EN
In order to investigate the mechanism underlying the reported nonlinear at-rest coefficient of earth pressure, K 0 of clays at high pressure, a particle-scale model which can be used to calculate vertical and horizontal repulsion between clay particles has been proposed.
This model has two initial states which represent the clays at low pressure and high pressure, and the particles in this model can undergo rotation and vertical translation.
The computation shows that the majority of particles in a clay sample at high pressure state would experience rotation during one-dimensional compression.
In addition, rotation of particles which tends to form a parallel structure causes an increase of the horizontal interparticle force, while vertical translation leads to a decrease in it.
Finally, the link between interparticle force, microstructure, and macroscopic K 0 is analyzed and it can be used to interpret well the nonlinear changes in K 0 with both vertical consolidation stress and height-diameter ratio.
