Abstract:: Aimed at the representative project in the piers,which is protected by the downstream sediment storage dam,this paper has studied local scour in piers and defensive function of the sediment storage dam by means of hydraulic model tests.In primary conclusions,as a kind of protective measure,the sediment storage dam is feasible,which can control backward erosion near these bridges have no enough buried depth,and its function of alleviating scouring depth is very obvious based on the study.The formula of local scour depth near piers protected by the sediment storage dam,deduced from the paper,will provide references for practices.
