Numerical Investigation of the Bearing Capacity Factors Using the Finite Element Method
This paper aims to investigate the bearing capacity factors (Nc, Nq, and Nγ) of a strip footing, resting on the surface of a cohesion–frictional soil medium, using the displacement-based finite element method. The analysis is carried out by considering both associated and non-associated flow rules. Both smooth and rough footings are considered for the analysis, and the bearing capacity factors are estimated for a wide range of friction angle and dilation angle of the soil. Results reveal that as the dilation angle of the soil increases, bearing capacity factors also increase and this increasing trend intensifies as soil friction angle increases. Nγ values are highly dependent on both the roughness and width of the footing. It is observed that Nγ values are higher for the rough footing surface than the smooth one, and the values decrease as the footing width increases. A comparative study between the present analysis and the previous investigations is carried out, and it is found that the present results are in a good agreement with the results obtained by the previous researchers. Finally, the fuzzy reliability analysis is performed to identify the effect of the coefficient of variation of soil friction angle and the spatial correlation length on the probability of failure of footing considering spatial variability of the soil parameters.
