This paper presents the results of the assessment and prediction of the dynamic behavior of earth dams of various heights, taking into account large strains (geometric nonlinearity) and inhomogeneous features of structures under multi-component kinematic effects. A mathematical model, methodology and algorithm for estimating dynamic behavior of earth dams taking into account inhomogeneous features of structures and large strains in spatial and plane statements are given. Dynamic behavior of the models of the Pachkamar, Gissarak and Nurek earth dams has been studied taking into account large strains and inhomogeneous features of structures in various pre-resonant and resonant modes under multi-component kinematic effect. A number of new effects associated with the manifestation of large strains in the structure under various dynamic influences are revealed.

“…In recent studies of structure oscillations, the use of a plane model of structure under one-component effect is mainly considered, and in rare cases two-component kinematic effect [7][8][9][10][11][12][13][14][15][16]. Therefore, in this paper an attempt is made to investigate the oscillations of various earth dams using the spatial model of a structure, taking into account viscoelastic properties of soil and the inhomogeneous features of a structure under one-component acceleration of an earthquake.…”

“…In assessment of the dynamics of considered dams, the order of solved systems of integro-differential equations reached 1700. Systems of integro-differential equations (7) with initial conditions (8) are solved by the Newmark method [20]. Using the procedure of the Newmark method, the system of integrodifferential equations ( 7) can be reduced to an algebraic system of equations…”

Mathematical statement, methods and algorithm to solve the problem of steady-state forced vibrations of a structure are given in the paper using spatial model with account of viscoelastic properties of material of various structures and their elements under one-component kinematic effect. The results of study of earth structure oscillations under one-component kinematic effect are presented. It is stated that:A. for the structures under consideration in dynamic calculations it is desirable to use a spatial model; B. viscoelastic properties of soil under the load effect slightly reduce the amplitude of oscillations, and after effect cessation these properties lead to a sharp attenuation of structure oscillations.

Mathematical statement, methods and algorithms of assessment of stress-strain state of earth dams with account of elastic-plastic, moist properties of soil and finite strain, structural heterogeneity of structures under static effects, are presented in the paper. Stress-strain state of three erected structurally heterogeneous earth dams of different heights was studied with account of elastic-plastic, moist properties of soil and large strains in a structure. In the process of investigation it was revealed, that an account of elastic-plastic properties and moisture content of soil, as well as large strains and heterogeneity of a structure, qualitatively and quantitatively vary the state of high earth dams, increasing arch effect for vertical stresses and horizontal stresses in the base of a dam, changing stress state of a structure on the whole and bringing the drop in pressure on the contacts of different parts of a structure
