1. The Engineering Problem A circular footing (radius 1 m) is to support a column load of 1 MN on a dry sand layer 10 m thick, underlain by rock.

Goal : Compute settlement under working load and check if the bearing capacity is sufficient. Soil model : Mohr‑Coulomb (elastic‑perfectly plastic).

Why this tutorial? – It’s axisymmetric (2D but represents a 3D circular footing), computationally light, and introduces key Plaxis concepts. plaxis tutorial

2. Project Setup (Input) 2.1 Start a new project

Project title : “Circular footing – sand” Model dimensions : ( X = 5,\text{m}, Y = 10,\text{m} ) (half of the footing width because of symmetry) Model type : Axisymmetric Elements : 15‑node triangles (better accuracy for deformations)

2.2 Define soil and material

Material name : “Sand” Model : Mohr‑Coulomb Drainage type : Drained (since sand, long‑term loading) Parameters :

(\gamma_\text{unsat} = 17,\text{kN/m}^3) (E' = 30,\text{MPa}) (\nu' = 0.3) (c' = 1,\text{kPa}) (small cohesion to avoid numerical issues) (\phi' = 35^\circ) (\psi = 0^\circ) (non‑associated flow rule)

2.3 Geometry creation

Draw a rectangle : 5 m wide, 10 m deep. Assign soil set : “Sand” to the whole rectangle. Add footing (as a plate element):

Draw a line at the top edge from (x=0) to (x=1) m. Convert to Plate with:
