Abstract

This technical briefing provides a summary of the findings and assessments presented by the DSI (State Hydraulic Works, Türkiye) team during the ICOLD 2023 meeting regarding the performance of dams during the seismic events that occurred in February 2023. Two powerful earthquakes with Moment Magnitudes (Mw) of 7.7 and 7.6 struck the Eastern Anatolian Fault Line, impacting several dams in the region. The seismic activity resulted in significant lateral displacements, settlements, and cracks in the dam structures. For the first earthquake, peak acceleration recorded at the nearest station (TK4614 – Pazarcik) was 2.21 g, for the second earthquake, peak acceleration recorded at the nearest station (TK4612 – Goksun) was 0.59 g. The presentation at the conference, as reported here, provided valuable insights into the performance of the dams during and after the earthquakes.

ICOLD 2023,瑞典哥德堡-土耳其2023年2月地震事件的经验
本技术简报提供了DSI(国家水利工程, rkiye)团队在ICOLD 2023会议期间就2023年2月发生的地震事件期间大坝的性能提出的调查结果和评估的摘要。两场矩震级分别为7.7和7.6的强烈地震袭击了东安纳托利亚断层线,影响了该地区的几座水坝。地震活动导致大坝结构显著的侧向位移、沉降和裂缝。第一次地震,最近台站(TK4614 - Pazarcik)记录的加速度峰值为2.21 g,第二次地震,最近台站(TK4612 - Goksun)记录的加速度峰值为0.59 g。会议上的报告,如这里所报道的,对地震期间和地震后大坝的表现提供了有价值的见解。
