    Study on Model and Tests of Sheet Pile Wall with a Relieving Platform by Ming Zhang, Wei Wang, Ronghua Hu, Ziyi Wang

    Published 2020-01-01
    “…Therefore, the Earth pressure behind the bottom wall is larger than the calculated value by the Rankine theory. Finally, the displacement of the rib pillars is greater than the calculated results using the finite difference method and exceeds the standard requirements, owing to the failure of the retaining wall, and the unloading board needs to be constructed to improve the retaining wall’s behaviour. …”
