В работе представлены результаты инструментальных сейсмологических исследований территории Шульбинской ГЭС, выполненных с использованием пяти временных пунктов наблюдений (SB1–SB5). Произведен анализ спектральных характеристик микросейсмического шума, определен отклик грунтов методом HVSR, проведен анализ отношений амплитуд на разных станциях, полученных по записям землетрясений и взрывов для разных типов волн.</p><p>Показано, что исследуемая территория сейсмически неоднородна: наиболее выраженное локальное усиление сейсмических колебаний выявлено на насыпной плотине (пункт SB1) – приращение интенсивности по шкале MSK-64 составляет 0,7–0,9 балла, тогда как на остальных пунктах значимого увеличения интенсивности колебаний по отношению к эталонной станции не отмечается. Выявленные отличия связаны с грунтовыми условиями, показателем которых является значение Vs30, определенное проведенными сейсморазведочными работами по 10 профилям. На основании согласованных результатов HVSR и анализа волновых форм событий даны рекомендации по необходимости организации постоянного мониторинга состояния плотины сейсмическими методами.</p></abstract><trans-abstract xml:lang="en"><p>The Shulbinsk Hydroelectric Power Plant (HPP) is a critical infrastructure facility with a high level of engineering responsibility, necessitating a detailed assessment of local seismic hazard. This study presents the results of instrumental seismological investigations conducted within the Shulbinsk HPP area using data acquired from five temporary observation sites (SB1–SB5). Spectral characteristics of ambient seismic noise were analyzed, site response was evaluated using the Horizontal-to-Vertical Spectral Ratio (HVSR) method, and the obtained results were compared with amplitude ratios derived from recordings of earthquakes and quarry blasts.</p><p>The results indicate significant seismic heterogeneity across the study area. The most pronounced local amplification of seismic ground motion was identified at the embankment dam site (station SB1), where the increment in seismic intensity reaches approximately 0.7–0.9 points on the MSK-64 scale. In contrast, no significant increase in seismic intensity was observed at the remaining observation sites. The identified differences are associated with local soil conditions and low Vs30 values within the embankment body. Based on the consistency between the HVSR results and waveform analyses of recorded seismic events, recommendations are provided regarding the implementation of continuous seismic monitoring of the dam condition.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Шульбинская ГЭС</kwd><kwd>сейсмическая опасность</kwd><kwd>сейсмическая станция</kwd><kwd>сейсмическое микрорайонирование</kwd><kwd>HVSR</kwd><kwd>сейсмические шумы</kwd><kwd>приращение интенсивности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Shulbinsk Hydroelectric Power Plant (HPP)</kwd><kwd>seismic hazard</kwd><kwd>seismic station</kwd><kwd>seismic microzonation</kwd><kwd>HVSR</kwd><kwd>ambient seismic noise</kwd><kwd>seismic intensity increment</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Агентства Республики Казахстан по атомной энергии в рамках научно-технической программы BR24792713 «Развитие атомной энергетики в Республике Казахстан»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Карта сейсмического районирования СССР.
