Numerical Study of Behavior of Machine Foundations on Geogrid and Grid-Anchor Reinforced Sand under Dynamic Loading

Where the foundations of structures such as machines and compressors are subjected to dynamic loading with amplitude less than their allowable bearing capacity, the concern exists often for the amount of uniform and non-uniform settlement of such structures. This paper deals with the effects of using the new generation of reinforcements for the purpose of reducing the permanent settlement of these foundations under the influence of different percentages of the ultimate bearing capacity. Other items such as the type and the number of reinforcements as well as the number of loading cycles are studied numerically and experimentally. The studies show that by using the new generation of reinforcements and increasing the number of their layers in the same proportion as that of the dynamic load being applied, the amount of permanent settlement is reduced.
