• SETTLEMENT OF A CIRCULAR FOOTING ON SAND (LESSON 1) 3 SETTLEMENT OF A CIRCULAR FOOTING ON SAND (LESSON 1) In the previous chapter some general aspects and basic features of the PLAXIS program were presented. In this chapter a first application is considered, namely the settlement of a circular foundation footing on sand. This is the first step in becoming familiar with the practical use of the program. The general procedures for the creation of a geometry model, the generation of a finite element mesh, the execution of a finite element calculation and the evaluation of the output results are described here in detail. The information provided in this chapter will be utilised in the later lessons. Therefore, it is important to complete this first lesson before attempting any further tutorial examples.

3.1 GEOMETRY Figure 3.1 Geometry of a circular footing on a sand layer A circular footing with a radius of 1.0 m is placed on a sand layer of 4.0 m thickness as shown in Figure 3.1. Under the sand layer there is a stiff rock layer that extends to a large depth. The purpose of the exercise is to find the displacements and stresses in the soil caused by the load applied to the footing. Calculations are performed for both rigid and flexible footings. The geometry of the finite element model for these two situations is similar. Hereafter Legendado. The rock layer is not included in the model; instead, an appropriate boundary condition is applied at the bottom of the sand layer.
