“…The load pattern is also a key factor affecting soil arching. It has been observed that soil arching deteriorates under a local surface load [6,7]; meanwhile, the dynamic load exerts a greater influence on soil arching than the static load [8,9]. It is found that the extent of degradation owing to soil arching increases with the load amplitude and frequency [10].…”

A series of trapdoor experiments and DEM simulations were carried out in this study to examine the arching effect in granular materials, with the focus being on the influence of the direction for particle deposition. In the tests, particles (e.g. rice grains, PVC particles and nylon particles) were dropped as if they were raining at different directions to construct granular material layers with various fabric orientations. It is shown that the mobilization of arching effect depends on the direction of particle deposition, with the arching ratio ρ increasing at first and then decreasing. The arching effect is the weakest at a deposition angle of θ = 30° in obliquely deposited granular masses. It is also found that the vertical displacement of particles in the ultimate phase increases initially; it then decreases with the variation in the orientation of particle deposition, and the largest displacement occurs at θ = 30°.
