| description | One of the earliest earth retention technologies used in civil engineering projects is sheet pile walls. Therefore, in this work, a numerical analysis using Plaxis 2D was performed to investigate the behaviour of laterally anchored retaining system in sandy soil, focusing on the anchor force, lateral displacement, and maximum bending moment. The effects of anchor location and number on wall and soil deformations were investigated for various wall heights. When anchored-sheet-piles were used instead of cantilever sheet piles, the results showed a significant reduction in both wall deformation and bending moment specially at high dredging levels. In addition, while having numerous anchor levels is the most approach to minimize wall and soil deformations. Also, the findings revealed that adopting the one-anchored sheet pile wall can greatly decrease the maximum wall displacement by about and 59.16%; which occurs at 0.4H; as well as reduce the maximum bending moment by about 85.63%; which occurs at 0.5H, comparing with the cantilever sheet pile wall at dredging depth (H) = 5m. At a deeper dredging depth (H=9m), the maximum lateral displacement and maximum of wall were reduced by 88 %, and 86 %, respectively. Also, at H= 9m, using the second level of anchors can also reduce the maximum bending moment on the wall by more than 83.55 %. |
