The Influence of Basin Excavation on the Sheet Pile Structure
In this paper, the basin excavation process is numerically simulated by using the geotechnical engineering software PLAXIS, and the bending moment, deformation and anchor bar tension of sheet piles under different excavation methods are obtained. The influence in different basin excavation methods on internal force and deformation of the sheet pile is studied by the non-linear finite element method. The results show that, if the construction process was piling before excavation, the maximum bending moment at mid-span, the maximum bending moment in buried section, the maximum horizontal displacement and anchor bar tension of the sheet piles would be bigger than the results without considering the influence of basin excavation. Therefore, the influence of basin excavation sequence should be seriously taken into account in the sheet pile design and construction.
