Abstract

Arching in soils occurs when there is a transfer of forces between a stationary and yielding soil mass. The relative movement in the soil results in a redistribution of stress in the soil. Arching in soil mechanics is demonstrated in both natural scenarios and man-made structures such as in karstic soils, in tunnel construction or in the collapse of mine workings. Physical model tests were conducted in a geotechnical centrifuge to investigate arching and mechanisms of deformation in granular soils over a void using a trapdoor model. The experiments allowed visual observation of the evolution of the arching mechanism with increasing trapdoor displacement. Discussion is made of the load transfer mechanism, the shape of the arch and the ultimate load reached in the arching.
