Digital modeling and analysis of the movement of the foundation of a hydro-reclamation dam in a promising technology for the formation of water resources

Abstract

In the south of Russia there are mountain ranges that are not inhabited and for the most part cannot be involved in active agricultural turnover, excluding cattle breeding. But how are the catchment areas where precipitation runoff is formed, the mountain slopes are used by nature itself. We propose, according to the new technology, to transfer the accumulation of atmospheric precipitation into mountain gorges, places created by nature itself, designed to solve such problems. It is proposed to accumulate precipitation runoff both in underground and above-ground reservoirs, which makes the functioning of such systems the least affecting the ecology of the area, and in most cases even ennobling their locations. Buttress dams recommended for use when creating aboveground reservoirs in mountainous areas, located in difficult geological and hydrogeological conditions, certainly require additional research and are the subject of research. The purpose of the research was to study the movement of the base of a hydro-reclamation dam, when working in mountainous conditions, performed using digital modeling and analysis. The applied research methods were based on specialized digital calculation complexes designed to solve such problems, namely, to calculate the condition of soils. The Midas GTX NX software package was used, and the wxMaxima complex was used to develop a mathematical model and its digital study, which allowed, firstly, to calculate the displacements at the base of the dam S, while the calculations were made in the form of a numerical experiment, that is, with a set of a large digital array of data linking the displacement at the base of the dam from the pressures in the upper and the lower reaches. In turn, processing of the data array made it possible to obtain a mathematical model, then visualized, on which such actions as constructing level lines and obtaining local mathematical equations with a representation of their graphical interpretation were performed. The applied analysis revealed the degree of influence of the factors accepted for the study on the movements at the base of the dam, noting that almost any pressure from the upstream side, in the analyzed range, significantly affects the movement, while the values of the same factor from the downstream side are at least an order of magnitude less.
