Abstract: |
One
of the most common methods to measure soil mechanical properties (namely
cohesion and internal friction angle) is direct shear box test. In this paper
the development of a three-dimensional (3D) discrete element soil model for
simulation of a cohesive soil’s direct shear test is presented. The aim was
to calibrate the properties of the Hertz-Mindlin
with bonding contact model available in EDEM software to the results of real
direct shear box test. The cohesion and internal friction angle were
calculated from the equation of the Mohr- Coulomb line of the soil model.
Results show that direct shear laboratory test can be simulated very well
using discrete element method (DEM). The model’s calculated cohesion and
internal friction angle values and the corresponding mechanical properties of
real cohesive soil were in good agreement with relative error of 4.44 percent
and 4.66 percent, respectively. |
