Vertical Stresses within Granular Materials in Silos

vertical stresses within the granular material contained within the silos are significantly less than that expected from the overburden weight. The dependence of arching on material properties and the geometry of the silo is studied through several laboratory trials. Sand, placed at 30% relative density, was used in the laboratory model tests.

Vertical stress in the ground

Calculating vertical stress in the ground When a load is applied to soil, it is carried by the water in the pores as well as the solid grains. The increase in pressure within the porewater causes drainage (flow out of the soil), and the load is transferred to the solid grains.

The lateral pressure would be the same as the vertical pressure. It would increase directly with depth, so that a diagram of pressure would be a triangle. As will be developed further on, the sand will also cause a triangular horizontal pressure. However, it has an internal strength which makes the lateral pressure less than the vertical pressure.
