Abstract

Extreme settlement can lead to serviceability complications during shallow foundations design. Since Settlement controls the principle design criterion when it is related to the bearing capacity of soils, the estimation of shallow foundation settlement above loose sandy soils is a highly complex problem. For important structures such as bridges, power plants and earth dams, etc. settlement has to be reduced to ensure the stability of engineering structure, with another word any additional settlement could lead to successive structural damage when it exceeds the allowable. In this a model of (10×10×10) m with loose sand was used to investigate the effect of shallow various parameters by using PLAXIS 3D program which was used to solve many geotechnical problems. The program has been used to investigate effect (applied load intensity 100, 150, 200 KN, shape (circular square), width of foundations (0.75, 1, 1.5) m, internal friction angle of underlying soil (24, 33, 37) degree and effect water tables existence beneath the foundation). It was concluded that the shape, friction angle, modules of elasticity with was estimated based on a relationship which showed a good match with other available relationships predicted by powells and Water table existence which it doubles the settlement as it exist. Based on test results critical values were discussed and recommended.
