A finite element model (FEM) is developed to analyze the problem of seepage flow of water under concrete dams with sheet piles. The model was developed using the finite element software ANSYS, based on equivalent thermal analysis and correlation with seepage performance. The issue of water seepage under concrete dams is addressed mathematically. In this study, the effects of several parameters on porous soil seepage velocity distribution are studied. Sheet pile parameters were varied in depth, location and number of sheet piles. The sheet pile with variables of 0, 1, 2, and 3 pieces, location of 0, 0.5, and 1 of dam width, and the depth of the sheet piles varying as 2 and 4 m, respectively. The developed FE models were verified by a previous study and used for further parametric studies. It was concluded that increased sheet pile depth reduces the seepage flow. In addition, the location of the sheet pile is an important factor in seepage velocity, as it might increase the flow away from dam toe in a similar fashion to dam depth effects. Moreover, increasing the number of sheet piles further reduces the seepage velocity in comparison to usage of a single sheet pile. The sheet pile configuration and parameters are integrated with each other and each factor influence the others, resulting in various seepage flow patterns. This study demonstrates that FE modeling can effectively predict seepage flow under concrete dams with sheet piles. [ABSTRACT FROM AUTHOR]
