Numerical study of the kinematic parameters of an earth dam in a model experiment

To assess the convergence and stability of the methods for predicting the residual life of pressure hydrotechnical structures of general impact and gas-dynamic effects, a comparison of the analytical and numerical solutions was carried out by applying it to a mixed boundary value problem, cumulative initial and boundary conditions. The article deals with the problem of loading a pressure head hydraulic structure with a given profile. To assess the convergence and stability of the developed numerical method for solving the problem of the spatial motion of a pressure head hydraulic structure, taking into account the interaction with its base, a comparison was made of the analytical and numerical solutions of the problem of loading a pressure head hydraulic structure with a known cross section, and a numerical solution of the problem of dynamic loading of an absolutely rigid 6- a faceted stamp simulating an experiment on dynamic loading of an absolutely rigid round die, the results obtained by independent calculation methods are compared with the available experimental data.
