The issues of seismic stability of hydraulic engineering structures (HES) in seismically active regions of South Kazakhstan are considered. The seismic impacts on dams, reservoirs and irrigation systems are analyzed, and the possible risks of failure are assessed. Methods of numerical modeling, laboratory tests and statistical analysis of earthquake data for the last 50 years are used in the work. Modern approaches to improving the seismic resistance of hydraulic engineering facilities are considered, including injection technologies for reinforcing the soil base and the use of seismic isolating materials. The results of experimental studies confirming the effectiveness of the proposed solutions are presented. It is revealed that the introduction of these technologies allows to reduce the risk of soil liquefaction by 40% and to reduce the transmitted seismic loads on the structure up to 50%.
