Abstract EN
Through numerical simulation based on the particle flow method, DEM numerical test samples were generated with the results of laboratory tests on standard sand.
The method consists of the use of gravity deposition and radius expansion modeling of irregular sand particles, where samples of the biaxial test are assembled by generated long particle units.
Different steps of deposition or initial stresses were applied during the sample generation process in order to simulate different sample states.
The loads from the horizontal and vertical directions are, respectively, applied to samples, and then the stress-strain curve and macroscopic mechanical parameters are acquired.
The numerical experiment results show that the gravitational deposits have significant impact on the major axis orientation arrangement of particles and on the average coordination number, as well as the initial stress has a significant effect on it.
There is a remarkable effect on the stress-strain curve and on the acquired mechanical parameters as a result of the application of load to samples from the horizontal and vertical directions.
The sand samples show an obvious property of inherent anisotropy and stress-induced anisotropy.
