Title: Riprap Stability in the Vicinity of a Bridge Pier Fitted with a Collar in the Rivers Bend
Abstract: 3 Abstract: The use of riprap stones to deal with scour problems is very usual in civil engineering practice. Riprap particles are mostly failures with passing time by during floods and so regarding to increase riprap stability is a necessary issue and it has been considered as main object in this research. Several researches have been conducted during the past three decades in straight flumes. Experiments were conducted using a 180-degree laboratory flume bend for three various sizes of collars and four sizes of riprap. The cylindrical model pier was installed at 60-degree position with clear-water conditions. Analysis of the experimental results showed that the relative rock size significantly affected the stability number for cylindrical piers. Although the results show that riprap layer with collar widths of 3b.2b.1.5b (b, pier diameter) is, respectively, 8%, 15% and 22% more stable than that an unprotected pier.
