WITHDRAWN: Utilization of filter for seepage phenomenon reduction under hydraulic structures

Abstract

Abstract Water movement under hydraulic structures through a permeable layer of soil is considered as one of the main causes of failure of hydraulic structures. Therefore, this study aims to minimize the influence of water movement under hydraulic structures by using a filter. The case was simulated using the finite element analysis software ANSYS where many valuables were studied such as head of water, depth of upstream cut off wall, filter depth, and filter location. Such variables usually influence the uplift pressure, exit gradient and seepage discharge, which control the performance of the hydraulic structure. The results have shown that the position of filter at downstream leads to increases the seepage discharge and exit gradient, while at upstream, it reduces the uplift pressure significantly.
