Design of retaining wall using finite element method

Retaining walls are structures built to keep the ground volume behind safely without collapsing. In this study, 3, 4.5 and 6 meter high retaining walls were modeled by taking into account the preliminary dimensioning of the retaining walls used with the finite element method. Analyzes were made at three different wall heights, at varying groundwater levels of 0, 1, 2, 3 and 4 times the floor width. In addition, the 4.5 meter high retaining wall was analyzed with front fill ground heights varying as 0, 25, 50, 75, 100, 125, 150, 200 and 225 cm on sandy ground where there is no groundwater. and were examined in terms of cutting forces. According to the results, as the wall height increases, the loads transferred to the wall increase. At the same time, as the height of the front filling material increases, the loads transferred to the wall appear to decrease. Therefore, instead of strengthening the wall as the height of a retaining wall increases, using pre-fill can be used as an alternative solution to reduce the loads transferred to the wall.
