The paper provides a detailed analysis of the current state of the problem. A mathematical model is presented to determine the dynamic behavior of earth dams, considering the viscoelastic properties of soil, using the hereditary Boltzmann-Volterra theory with the A.R. Rzhanitsyn kernel under periodic kinematic impacts. To solve the problems considered, the finite element method and complex arithmetics were used to reduce integrodifferential equations to a high-order complex algebraic equation. The accuracy of the methods was verified by solving test problems. Steadystate forced vibrations of the Pskem earth dam 195 m high are studied considering the real geometry and soil properties under resonant vibration modes. It was stated that the largest stress amplitudes in the body of the dam occur not only under the first resonance, but they can occur under other dense spectra of the eigenfrequencies of the dam, due to the interaction between close natural modes of vibration. The strength of various sections of the dam body was tested under kinematic impact using the Coulomb- Mohr theory of strength; the most dangerous sections of the dam were identified in terms of the highest stress.

“…Such work requires adequate performance, since in low-pressure hydrotechnical constructions, that is, in objects of class IV, as a rule, the installation of control-measuring instruments is not envisaged [9], therefore, specialists mainly focus attention on qualitative, partial-number diagnostic indicators, which are determined on the basis of nature or visual observations and the simplest measurements. So, one of the observations of nature is an important issue in determining the deformation (drowning, deviation, horizontal smoothing) of structures and their floors [10][11][12].…”

“…The problem of spatial calculation of earth dams is a particularly laborious task [14][15][16]. Usually, when assessing the stress-strain state of dams located in wide gates, it is sufficient to use the conditions of plane strain; however, the use of plane calculation schemes for earth dams located in narrow gates requires more thorough verification of accuracy in assessing the SSS of structures.…”

“…If the above ratio is violated, then the spatial nature of dam operation is manifested. In [5,6,14,15,16] it is shown that the accuracy of dam calculation changes not only under the action of static load but under dynamic effects as well.…”

A comparative method for estimating the stress-strain state of earth dams under the effect of static load is given in the paper using spatial and plane-strain models. The results of assessment of stress-strain state of several earth dams using these methods are given. Analysis of the results obtained allows us to conclude that a plane calculation model gives results almost identical to the ones obtained with spatial model; in future that can be the basis for developing recommendations on the use of certain calculation models. Some features of stress state in a spatial case are revealed, indicating the occurrence of dangerous areas with the greatest stresses.
