THE APPLICATION OF WAVE THEORY FOR SEISMIC EFFECTS MODELING ELASTIC STRESSES IN KURPSAY THE DAM WITH A SOIL BASE WITH EMPTY RESERVOIR

Abstract

Discusses some problems of numerical modeling of seismic safety of concrete dams Kurpsay with a soil base by wave action. The dam is modeled with the reservoir. The program complex allows to solve problems under non-stationary effects on complex objects. On the basis of the finite element method in displacements the algorithm and the program complex for solving linear flat two-dimensional problems of wave theory of elasticity. A comparison with the results of the mixed finite element method. The maximum tensile stress occurs on the upper rear contour of the dam. Elastic contour stress on the faces of the dam is almost a mirror reflection of one another, that is, antisymmetric.
