АНАЛИЗ ФАКТОРОВ СЕЙСМИЧЕСКОЙ ОПАСНОСТИ ДЛЯ ГИДРОТЕХНИЧЕСКИХ СООРУЖЕНИЙ В ЮЖНОМ КАЗАХСТАНЕ

Abstract

Seismic hazard is a significant threat to hydraulic structures, especially in regions with high seismic activity, such as South Kazakhstan. The present study is devoted to the identification and analysis of key factors determining seismic stability of hydraulic structures in this geographical zone. The work includes systematisation of data on geological and tectonic features of the region, as well as characteristics of local soils, which significantly affect the amplification of seismic waves. The study classifies hydraulic structures in the region, identifies the most vulnerable structures and typical seismic failure scenarios. Special attention is paid to the study of the role of hydrodynamic effects, the influence of water level in reservoirs and operating conditions on the overall stability of structures.

Based on numerical modelling and analysis of field data, recommendations were developed to minimise seismic risks, including the selection of optimal structural solutions, the use of modern calculation methods and the introduction of innovative materials with enhanced stability characteristics. In addition, measures are proposed to improve the system of monitoring the condition of structures and to develop effective emergency response strategies. The results obtained can be applied in the design, reconstruction and operation of hydraulic structures in earthquake-prone regions, as well as in the development of national standards and regulations.
