| Abstract | ||
| This paper aims to study the effect of sheet pile on seepage characteristics under the hydraulic structure floor through soil consists of two layers that for convergence to exact case similar to studying case in nature. The effect of changing each of the effective water head, the sheet pile location under the floor of hydraulic structure, the sheet pile penetration depth in the soil layers and the arrangement of soil layers was done. In this paper the seepage characteristics was studied experimentally (Sand Model) and Numerically (Geo-Studio SEEP/W Model). The experimental and numerical results confirmed that the uplift pressure values decrease along the floor in case of upstream sheet pile depth was less than half depth of coarse sand and when the upper layer was coarse sand. The comparisons between sand model results and numerical results give a good agreement | ||
