the effect of submergence percentage of the submerged piles on the reduction of scour in bridge abutments
Authors
abstract
scour around hydraulic structures is an inevitable phenomenon . recognition of this phenomenon and dealing with it is an issue considering which will ensure the project success . local scour at piers has been reported as the most important factor in the destruction of the bridges . the use of submerged and non-submerged piles is one of the scour control methods . submerged piles have been rarely used to assess scour . in the present study, the results of some tests with different flow rates and submergence percentages are given in the bridge abutment . the tests have been conducted at clear water conditions in a flume with length of 14m , width of 60cm and depth of 60cm . the results show that the increase in the submergence percentage of piles has a significant role in reducing pier scour.
