Active Arching of Sand During Static Loading
Tests were performed to provide quantitative information on soil arching over a buried structure. Idealized small-scale structures were buried in prepared specimens of dry NCEL test sand, and static over-pressures of various magnitudes up to a maximum of 150 psi were applied to the surface of the specimens. Foundation area and depth of soil cover over the structures were the major variables during the tests. Measurements were made to evaluate the inter-relationships between depth of soil cover, static overpressure, soil stiffness, structural motion, and soil arching. The magnitude of soil arching over a particular soil-structure system subjected to static loading was found to be a function of a factor accounting for the geometry and the relative stiffness of that system. Geometry is accounted for by the perimeter area ratio of the structure multiplied by the depth of soil cover. The stiffness portion of the factor relates the soil stiffness to the stiffness of response of the structure relative to the free-field soil. (Author)
