Bearing Capacity Estimation of Shallow Foundations on Layered Sand Strata Using Finite Elements Analysis

Das, Pragyan Paramita / Khatri, Vishwas N.

This paper presents a bearing capacity estimation of the rough strip and circular footings embedded in dense sand overlain by loose sand strata. Numerical study is carried out using finite element analysis (FE) wherein the soil was assumed to obey Mohr–Coulomb’s yield criterion with either associated (ψ = ϕ) or non-associated flow rule (ψ < ϕ). The bearing capacity was computed for different values of soil friction angle of the top and bottom layer (ϕ₁ and ϕ_2, respectively), depth of the footing (D_f) from the surface and the thickness of top dense layer (H). The comparison was made with those of the available literatures wherever applicable.
