Soil arching in the trapdoor problem was investigated via the physical model test and the discrete element simulation. Under the relatively low confining pressure in the physical test, it was found that the sequential transition of the vertical pressure from the trapdoor at the center to contiguous locations in a progressive manner. Uniformity of the particle size distribution in the physical test attributes unsuccessful generation of the resisting internal structure against the generation of… CONTINUE READING
