Settlement analysis of a large piled raft foundation

The subsoil in the area of the power plant consists of thick layers of sand divided by thin layers of clay and peat. Soil profiles at four different locations A to D are shown in Figure 1. The location of points A to D in respect to the foundation is shown in Figure 7. The thicknesses of most layers vary only little so that in the calculation model they are assumed constant in thickness. An exempt is the uppermost clay layer. This layer’s boundary to the underlying sand layer is assumed as an inclined plane.
