Özet
The major earthquakes that occurred in Turkey in February 2023 once again revealed the vital importance of the seismic design of dams. The earthquake records in critical locations in affected areas clearly show that the direction and relative magnitudes of the recorded accelerations have created findings that need to be re-evaluated. During the earthquakes, serious damage occurred in several earth fill dams due to liquefaction or excessive lateral spreading in the foundation soil and dam body, stability problems in the embankment slopes, and excessive crest settlements. This paper assesses the dynamic performance of the 40-meter-high homogeneous earth fill Arıklıkaş Dam, situated in the city of Osmaniye in southern Turkey, following its exposure to the destructive effects of the February 2023 earthquakes. For this purpose, a series of dynamic finite element analyses are performed to evaluate the dynamic response of the dam considering the near-fault effects and acceleration directions. Through a comparative analysis of the observed damages in the dam following the Maraş earthquakes with the analysis results, this study investigates the primary causes and mechanisms underlying the damages. A possible rehabilitation alternative is also evaluated to satisfy the required safety level for returning the dam to service.
