The numerical modelling of the cylindrical shafts can be done using finite element method in axisymmetric or three-dimensional conditions. For this study, the 3D finite element method has been used to analysed the cylindrical shaft’s behaviour regarding the earth pressure distribution, the vertical displacements of the soil and the horizontal displacements of the diaphragm wall. Thus, a parametric study has been carried out in which the cylindrical shafts radius, the length of the diaphragm wall and the excavation depth have been varied. For all the numerical models, the cohesive and cohesionless soil has been used. The results show the influence of all these parameters on the retaining walls’ behaviour. Also, the influence of the soil type is explained.
