RESEARCH ON METHODS TO REDUCE THE RISK OF FAILURE IN RESERVOIR STRUCTURES AND ENHANCE STRENGTH CHARACTERISTICS UNDER DEFORMATION

This article presents the results of research aimed at reducing the risk of failure in reservoir hydraulic structures and enhancing their strength characteristics under conditions of deformation. During the study, the physical-mechanical and granulometric properties of the materials used in the structure’s primary foundation and concrete mix were analyzed under laboratory conditions. Sand and gravel samples were tested in accordance with current regulatory requirements; parameters such as grain-size distribution, fineness modulus, bulk density, content of dust and clay particles, the proportion of elongated (needle-shaped) and flaky (plate-shaped) particles, and crushability indices were determined. It was established that the gravel has a bulk density of 1420 kg/m³ and a crushability grade of M1200. The results obtained are of significant practical importance for ensuring the stability of the foundations of hydraulic structures, mitigating the risks of deformation and collapse on embankment slopes, optimizing concrete composition, and guaranteeing the reliable and safe operation of reservoirs. The findings of this research contribute to the assessment of the technical condition of hydraulic structures and the enhancement of their long-term stability.
