Using discrete element methods, geotechnical engineers can create “virtual laboratories” to simulate conventional laboratory tests. In this study, three-dimensional DEM simulations of direct shear tests are coupled with equivalent physical tests on steel balls. The macro-scale response of simulations is compared with the physical test results to validate the discrete element model and to gain i...

In this paper, a bespoke stress and temperature controlled direct shear apparatus to test soil-geosynthetics interfaces is introduced. By adopting the apparatus, series of ‘rapid loading’ tests creep were conducted on Clay – Geosynthetic Drainage layer (GDL) assess functionality apparatus. The experimental results indicate that, modified can allow deformation behaviour under environmental durin...

The rockfill structures are widely constructed throughout the world and rockfills are largely used in these structures as main materials or filler materials. In the crust of earth dams, the rockfill materials role is to stabilize the body of the dam, however, the behavior of these materials in Particular their shear strength is not fully understood. In this study, different tests have been cond...

Cohesive-frictional soils are widely used in the construction of embankment structures and due to the method of construction, i.e. applying compactive efforts in the vertical direction in these cases, the occurrence of anisotropy in the soil strength and permeability seems to be inevitable. In this study, attempts have been made to evaluate the shear strength of c-f soils through modifying a l...
