| description | A methodology for determination of seismic accelerations in earth dams has been developed within the framework of seismic resistance wave theory. In this case we take into account an influence of the dam foundation and seismic wave emission into it. The methodology is based on numerical solution of the dynamic problem while using a finite difference method. A software program SGD “Determination of seismic acceleration in the earth dam” has been prepared on the basis of the developed methodology. The program allows to evaluate ordinates of calculation orthographic representations for acceleration throughout the dam height for all time moments. Thus, it is possible to obtain the most dangerous acceleration orthographic representations at direct and reverse seismic actions. The papers presents verification (compliance test) of calculated and observed seismic accelerations for the rock-fill dam of the Dnestrovskaya Hydro-Electric Power Plant No 1. The observed seismic accelerations have been obtained during experimental explosions. The calculated seismic accelerations have been obtained in accordance with the proposed methodology for determination of seismic accelerations in the earth dams. A comparative analysis of calculation results with the data of field observations has demonstrated that a maximum difference between extreme accelerations obtained by calculation, and during field observations, do not exceed 10.11 % for the dam crest, and 6.56 % for its bottom. The obtained results permit to recommend the developed program for engineering calculations of seismic accelerations in the earth dams. The program application will make it possible to determine seismic acceleration in the earth dam with sufficient reliability. |
