Özet

Surgu Dam, located in southeast Turkey was subjected to longitudinal cracks on the dam crest and simultaneous settlement on the upstream part of the day, during 5 May 1986 Malatya Earthquake. In the following, a brief account of the 5 May 1986 earthquake and the damage occurred in the dam is reviewed, and the results of a dynamic finite element analysis incorporating the non-linear soil properties are presented. It is observed that, a Newmark type permanent displacement analysis carried out under simulated earthquake motions agree well with the actual measurements made immediately after the earthquake. The Fourier amplitude spectrum of the transient motions recorded on the dam crest is also in good agreement with that of the computed spectra under the low-amplitude synthetic white-noise type base excitations.
