Numerical Study of the Failure Surface in Granular Soil Under Two Closely Spaced Strip Footings
This work aims to present a numerical study using finite element analysis using the model of plane strain performed on sand with two closely spaced strip footings. The calculations are performed using the finite element code Plaxis. The soil is represented by the nonlinear model with hardening of soil (Hardening Soil Model) is an elasto-plastic and hyperbolic model. A parametric study revealed the role of the distance between footings on the interfering factor (ζγ) and failure surfaces of soil under footings. The numerical results agree with the theory of Stuart .
