Geniş akarsuları geçen köprülerin yıkılmasıyla çok sayıda can kaybı, kamu ve özel mülk hasarları ve trafiğin aksaması gibi problemler yaşanabilir. Bu olumsuzlukların önlenebilmesi amacıyla planlama ve tasarım aşamalarında köprü yıkımına neden olabilecek tüm etkenler ele alınmalıdır. Geçmiş gözlemlere dayanarak köprü yıkılmalarının ana nedeninin orta ve kenar ayaklar etrafında oluşan aşırı oyulmalar olduğu söylenebilir. Ayaklar etrafındaki oyulma olayı oldukça karmaşık olup, bu olayı tetikleyen parametrelerde fazla miktarda belirsizlik bulunmaktadır. Temel derinliğinin gerçekçi olarak saptanabilmesi için ayaklar etrafındaki oyulma derinliğinin hassas olarak bulunması gereklidir. Bu çalışmada, dik köprü kenar ayakları etrafındaki temiz su oyulmasının zamana bağlı değişimini veren amprik ve yarı amprik yöntemler geliştirilmiştir. Temel derinliğinin güvenilirliği, amprik yöntemin Monte Carlo tekniğiyle çözümlenmesinden bulunmaktadır. Ayrıca bu uygulamanın gösterildiği bir örnek sunulmaktadır.

Scouring Reliability at Bridge Abutments Köse, Ömer; Yanmaz, Ali Melih (2010-01-01) Failures of bridges crossing wide rivers may cause a number of inconveniences, such as loss of several lives, damages to public and private properties, and traffic disruption. That is why various modes of bridge failures should be accounted for in the planning and design phases to compensate for such negative impacts. Based on the experience gained from past events, it is known that excessive scouring at bridge piers and abutments has been the main cause of bridge failures. The scouring phenomenon is relati...
Scouring reliability of bridge abutments Kose, Ömer; Yanmaz, Ali Melih (2010-12-01) Failures of bridges crossing wide rivers may cause a number of inconveniences, such as loss of several lives, damages to public and private properties, and traffic disruption.

Effects of collars on local scour around semi-circularend bridge abutments Daşkın, Süeyla; Göğüş, Mustafa; Department of Civil Engineering (2011) During severe floods, bed material around bridge piers and abutments are scoured by the flow and as a result, bridges are subject to damages. These damages are mostly unrepairable and can result in loss of lives and property. In this thesis study, abutment scour under clear-water condition was investigated and collars were tested as scour countermeasures around the abutments. The experimental study was carried out in a rectangular channel with an almost uniform cohesionless bed material of d50=1.50 mm for a...
Scour and scour protection at bridge abutments Kayatürk, Şerife Yurdagül; Göğüş, Mustafa; Department of Civil Engineering (2005) Bridge failures are mainly caused by scouring the bed material around bridge foundations during flood. In this study, scour phenomenon around bridge abutments is experimentally studied. Effect of abutment size, location and size of the collars placed around the abutments, time evaluation of scour hole around the abutment, scour characteristics of abutment and pier interaction were experimentally investigated. Scour measurements were conducted in a rectangular channel of 30 m long and 1.5 m wide filled with ...
Experimental investigation of local scour around bridge pier groups Özalp, Murat Can; Bozkuş, Zafer; Department of Civil Engineering (2013) It is an important task that design engineers in practice predict the local scour around bridge piers as accurately as possible because excessive local scour around bridge piers unbalance and demolish the bridges. Many equations have been proposed previously by various researchers, based on their experimental findings, but no general method has been developed so far due to the complexity of the topic. In the present study two new bridge pier groups were employed to investigate the inclination effect of the ...
