Conclusions

  1. 1.

    The most probable location and dimensions of residual deformations that could develop during an 8-point earthquake are determined by a review and analysis of the geological and seismotectonic conditions of the region in which the reservoir for the Zhinvala hydroelectric plant is being constructed. The kinematic characteristics of the primary (seismotectonic) and secondary (slide) residual deformations are evaluated.

  2. 2.

    The above-cited data are used to estimate the height of waves generated in the reservoir during various seismic events.

  3. 3.

    The results of specific numerical computation from Eq. (2) indicate that the maximum increase in the water level near the Zhinvala hydroelectric plant dam resulting from a slide from the bank in the right branch of the reservoir is 2.7 m; this is almost three times the value of this increase in the case of seismotectonic displacements in the right or left branches of the reservoir. The oscillation periods of the water range approximately from 3 to 14 min for all cases.

  4. 4.

    Computations performed on an electronic computer from the equation derived for the effects on the dam and reservoir bottom of seismic vibrations indicated that the maximum amplitudes of waves generated on the surface of the water will not exceed 1 m.
