Abstract

Reliability of coastal structure is mainly based on maintaining the specified functions of the structure set duringits design for a determined time interval and not reaching to the limit damage condition values due to the loadingforces of structural resistance. A reliability based risk model is applied to the revetments located in the regionbetween Piraziz-Sarp of the Black Sea coast highway by sampling the uncertainties of the random designparameters with probability distributions using physical properties of armor layer and significant wave height(Hs) of the study area. It is found that the factors affecting the reliability of the revetments are the armor layerslope (cotθ) and the relative stone density (Δ). Damage probability of the structure in its economical life is alsocalculated.

Özet

Kıyı yapısının güvenilirliği, yapının tasarımında belirlenen işlevleri belirli bir zaman aralığında sürdürmesi veyapısal dayanımın yük kuvvetleri etkisiyle limit hasar durum değerlerine ulaşmaması esasına dayanmaktadır.Çalışmada, Karadeniz sahil yolunun, Piraziz-Sarp arasındaki kesimde yer alan tahkimat yapılarına, koruyucutabakanın fiziksel özellikleri ve deniz yöresine ait belirgin dalga yüksekliği (Hs) değeri kullanılarak, rassaltasarım değişkenlerindeki belirsizlikleri olasılık dağılımları yardımıyla örnekleyen güvenilirliğe dayalı riskmodeli uygulanmıştır. Tahkimat yapılarının güvenilirliğini etkileyen faktörlerin, koruma tabakası eğimi (θ) verölatif taş yoğunluğu (Δ) olduğu belirlenmiş ve yapının ekonomik yaşam ömrü boyunca karşılaşacağı hasarolasılıkları hesaplanmıştır.
