Stress-strain state of earth dams under the effect of harmonic (seismic) load from the base of the dam is numerically studied in the paper. Rock fill dam has good culvert properties and its water saturation is considered to have no effect on mechanical characteristics and strength properties of rock; filtration flow mainly forms on the low-permeable core of the dam. Usually, the dam core consists of soft (loess) soil, therefore its water saturation significantly influences physical and mechanical properties of soil. A two-dimensional problem is considered for the cross section of a dam using the equation of state with allowance for structural changes in rock fill and moisture content of a dam core with low-permeable trapezium properties. For earth dams, as is known, a filtration flow is formed in the dam body. The problem is solved numerically - by the method of finite differences. The results are presented in the form of graphs and are analyzed.

In the article, the results of approbation of the developed technique of the refined numerical simula-tion of the dynamic stress-strain state of the three-dimensional system “ground base (earth foundation) – reser-voir – construction of the pressure head of the hydraulic system” under seismic influences. A comparison is made between two different ways of modeling the fluid interacting with the structure and the base of the hydroe-lectric power station. The issues of choosing the dimensions of the base unit and taking into account the inertial load from it, as well as the method of determining the initial seismic action, are touched upon.
