Local scour around rectangular abutment and their countermeasures by using sacrificial piles
One of the important issues in hydraulic engineering is inspection of local scour depth around bridge pier. Using piles is one of the ways for confronting local scour and erosion. In this study, the experiments were conducted in an 8m long, 0.5m deep and 0.25m wide flume. And the effectof using piles and number of them observed on the amount of scour in three different Frude numbers. The shape ...

متن کاملExperimental comparison of sacrificial piles and submerged vanes as scour countermeasures around bridge pier
An experimental study has been conducted on the effectiveness of two types of flow-altering countermeasures placed around a cylindrical pier under clear water condition, which include sacrificial piles and submerged vanes. Their arrangements follow the optimal configurations recommended in the published articles with some modification. The temporal evolution of maximum scour depth and its equil...
متن کاملTime Development of Local Scour around Semi Integral Bridge Piers and Piles in Malaysia
Scouring around a bridge pier is a complex phenomenon. More laboratory experiments are required to understand the scour mechanism. This paper focused on time development of local scour around piers and piles in semi integral bridges. Laboratory data collected at Hydraulics Laboratory, University of Malaya was analyzed for this purpose. Tests were performed with two different uniform sediment si...
متن کاملControl of Scour Around the Piles with Using Cable and Collar at the River
In this study, in order to examine the joint of the cable and the collar in control of scour around the bridge piles, experiments were carried out in a rectangular plexiglass flume as a direct path. The experiments were carried out using three different cable diameters, three different thread angles and three rounds of the cable threaded at a steady current in clear water. The results of this s...
