Abstract

Every year due to river floods a great number of river structures such as BRIDGE PIERs are collapsed. The most important reason for failure of BRIDGE PIERs is the occurrence of scour phenomenon at the bottom of these structures. One method of scour countermeasure is to set a protective device (i.e. collar) around BRIDGE PIER. Collars protect efficiently the riverbed against vortices system around pier and reduce SCOURING. In this research, the performance of series of rectangular collars with different size ratio (i.e. W/D =1.5, 2, 2.5) which seated horizontally in different elevations (Yc/D=- 0.2, 0, 0.2) in respect to bed level were investigated. Experiments carried out under clear-water condition and the results were compared with pier without collar and pier with circular collar. The results showed that the collar resting on and below the bed level have better efficiency compared with the collar resting above the bed level. As the width of collar increased, the performance of collar as a scour countermeasure also increased. Collars with size ratio (W/D) of 1.5,2 and 2.5 reduced SCOURING 14,29 and 49 percent respectively. The results also indicated that performance of rectangular collar in reducing scour depth and increasing equilibrium time is better than circular one.
