Abstract

Stress-strain state and non-stationary dynamic behavior of ground dam under kinematic action in the form of synthetic seismogram are studied in the paper by the method of finite differences. The regularity of deformation of dam material was taken as elasto-plastic one. Numerical results obtained are given in the form of graphs. The author of this paper worked out the methods using the finite-differential methods of M.Wilkins’ scheme and carried out the design of non-homogeneous ground dam with account of wave processes occurring in the body of the dam on seismic action. Numeric solutions of closed system of differential equations using different equations of state (elastic, elastoplastic and with account of rheological characteristics of ground) of dam material were obtained. Basing on results of the calculations dynamic behavior and stress-strain state of ground dam under seismic load in the form of record of synthetic seismogram were studied. The zones of formation of plastic flows of ground leading to a loss of bearing capacity and stability of the dam were revealed and the stability of dam slopes under seismic action was assessed.

Dynamic Design of Ground Dams Under The Action of Dynamic Loads

San Diego, California

Stress-strain state and non-stationary dynamic behavior of ground dam under kinematic action in the form of synthetic seismogram are studied in the paper by the method of finite differences.
