Russian engineers have been studying the world experience of CFRD design and possibility CFRD construction in the high seismicity regions of Russia. The report considers the behavior of the CFRD of 148 m height on a fractured rock foundation under seismic impact of 7 earthquake intensity (MSK-64 scale). Three soil zones were defined in the dam body: the transition zone under the slab, the central and the downstream parts. The analysis was carried out on the basis of 3D model of the structure - foundation by the finite elements method using ANSYS and LS-DYNA software. Total amount of the finite elements was about 150 thousands. The dam body and foundation were modeled by 8-node, the abutments - 4 and 6-node 3D elements, the concrete slab - by shell elements of variable thickness. There were also used contact elements. Static and seismic analyses were fulfilled. The static evaluation was carried out to determine the initial stress field from the dam dead weight and hydro-static. The seismic evaluations were carried out according to the non-linear dynamic theory; three-component seismic impacts were specified for the low border of the design area. Studied was the influence of the relationship of deformation module values of the central and the downstream parts on the stress-strain state of the dam and concrete slab. A result analysis of the numerical modeling of the dam and slab behavior under seismic impacts was carried out.
