Criteria truth computer simulation of frequency response curves of the free oscillations hillsides systems

The information database on the accuracy of the computed values of the frequency characteristics of free oscillations of a triangular-shaped dam rigidly fixed to a rock foundation decided by different authors is analyzed. As a result of the analysis of the influence of the finite element forms, a special criterion is proposed that allows to assign a minimum amount of the design of the target nodal masses. The results of a finite element calculation for finding the frequency characteristics of a complex large-scale object-consisting of mountain slope systems in the interrelation between themselves and with a deformable base-are presented. The shape of oscillations corresponding to five rock-frequencies with respect to a rock base is shown.
