Analysis of deformation processes in retaining walls of hydraulic structures requires the creation of fundamentally new methodologies and specialized equipment that will allow accurate measurement of various types of deformations: settlements, inclination of structures, angular displacements. During operation, the retaining walls are subjected to serious wave loads, the calculation and prediction of which is necessary for the design of the structures of berthing facilities, the conditions for mooring ships. To determine the characteristics of waves and wave processes, it is proposed to use the method of numerical modeling, which involves the formulation of a boundary value problem of mathematical physics and the development of a numerical solution to this problem. This method has been actively developing recently and is used to solve problems of determining wave loads and impacts on port hydraulic structures. On the basis of a mathematical model, a program is implemented that calculates the hydrodynamic processes occurring in channels of arbitrary shape, taking into account the Coriolis forces and friction. For the solution, the finite difference method (grid method) was used. As a result of applying this method, data are obtained that are convenient for plotting graphs. Also, the finite difference method is easy to program. Parallel programming methods can be easily applied to this code, which makes it possible to speed up the receipt of the result. Based on the model, the obtained data are compared with real hydrodynamic processes and conclusions are drawn. [ABSTRACT FROM AUTHOR] |
