The Bachlors thesis discusses the usage and theoretical background of the program Settle 3D. Settle 3D is mainly used for computation of ground settlement in various situations. We begin by introducing the four methods used to compute stress caused by surface load in order to calculate effective stress and settlement. We continue by explaining, in steps, how to input data for computation of several different situations. As we move on, we reserch some irregularities associated with graphical result output when dealing with rigid loads. Proof was found that Settle 3D correctly computes but inaccurately visualises settlement results under rigid loads. The effects of this flaw can be minimized by adding a larger number of field grid points. After that, we talk about irregularities that can occur if loads aren't properly defined. We conclude this thesis with the computation of two case histories. The results gaind through Settle 3D, were than compered to results gained by conventional methods. This was done in order to asses the programs accuracy, which in the end proved as adequate
