Sand - Wikipedia

Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most com

HOW TO CALCULATE PILE LOAD CAPACITY IN COHESIONLESS

Mar 31, 2015 · For non-plastic silt or very fine sand the above formula should be replaced by the following formula. The safe pile load capacity (Q s) can be obtained by dividing a suitable factor of safety by ultimate load capacity (Q u) as calculated above, i.e. Q s = Q u / F.O.S. The minimum value of factor of safety (F.O.S.) is taken as 2.5.
