Reducing Local Scouring at Bridge Piles Using Collars and Geobags

الملخص EN

The present study examines the use of collars and geobags for reducing local scour around bridge piles.

The efficiency of collars and geobags was studied experimentally.

The data from the experiments were compared with data from earlier studies on the use of single piles with a collar and with a geobag.

The results showed that using a combination of a steel collar and a geobag yields the most significant scour reduction for the front and rear piles, respectively.

Moreover, the independent steel collar showed better efficiency than the independent geobag below the sediment level around the bridge piles.
