SEISMIC STABILITY OF HYDRAULIC CONSTRUCTIONS TAKING INTO ACCOUNT THE YIELD STRUCTURE BEYOND ELASTICITY

Topics: 06.01.02 Land Reclamation, Recultivation, and Land Protection

Abstract:

The aim of the research was to study the effect of seismic load on the dams in mountain gorges, when the structures operate outside the elastic limit. The Black Sea coast of Krasnodar Territory is located in a zone with high seismic activity. There are no criteria for assessing reservoirs for the maximum design earthquake in the current regulations. At the same time, it has been found that the cities of the Black Sea coast of Krasnodar Territory are not provided with adequate fresh water during the summer period. The problem can be solved by developing technologies and technical means capable of accumulating precipitation with their subsequent use in the low-flow period. The optimum location of reservoirs on the coast are mountain gorges. Dams reliability and safety assessment was done by the limit state method. To analyze the impact on the seismic impact on structure specified by the accelerogram, the research of system in the STARK ES software product was carried out taking into account the effect on the hydraulic structure of the aquatic environment. Regulatory documents operating in construction currently do not regulate the dams construction in mountain gorges and in areas with high seismic activity. The use of modern methods of calculation and building materials allows to create safe structures that meet all the requirements of the reliability of hydraulic structures.
Key words: water supply, reservoir, dams, fresh water, water supply technologies, hydraulic structures.
