Abstract

 Hydraulic structures are commonly constructed on pervious soils through which seepage flow occurs and finds its way to the foundation. Most damages occur in a hydraulic structure may be attributed to the destructive effect of seepage. Design of hydraulic structures must include the analysis of the seepage flow beneath and around the structure with particular attention to the induced uplift forces, hydraulic gradients at the exit faces, water pressure on side walls and expected total seepage discharge. Most of researches deal with the the problem of seepage regards hydraulic structures as a two dimensional problem. Recent studies cope with three dimensional analysis including seepage around the structure to that occurs beneath the structure. Practically the seepage occurs beneath and around the hydraulic structure, therefore, the lateral seepage is a significant item and should be taken into consideration. The present study aims at controlling the seepage around a water retaining structure which has a horizontal floor provided with a single under floor cut-off. Two suggested control systems have been investigated, a lateral cut-off wall and a lateral relief filter. The problem has been investigated numerically as a three dimensional problem using the Finite Element Technique.
