Determination Of The Pressure Gradient In The Basis Of Concrete Hydraulic Structures Using The Regression Model In Complex Conditions

Abstract

In the absence of control and measuring devices, it is important to investigate filtration processes at the base of hydraulic structures located in complex conditions and to improve calculation methods that take into account changes in soils during operation. The purpose of the research is to determine the pressure gradient in the foundations of concrete hydraulic structures located in complex conditions of the republic. The methodology includes the theory of similarity and dimensionality, which is widely used in various fields of science and technology, as well as the theory of experiment planning with the aim of minimizing the experiment. The results showed that as the length of the structure increases, the pressure gradient initially decreases, and then stabilizes at a low level. This corresponds to a slower increase in water pressure compared to the length under the chosen conditions. The dependence of the pressure gradient on the length, taking into account the physical and mechanical properties of the soils of the structure's base, made it possible to ensure the safety of the structure in the absence of control and measuring devices for practice.
