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

Orazkhan B.; Kuttybekova С.; Baymakhan A.; Baymakhan R.

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
