Analysis about Bending Moment of Sheet Piles Retaining Structure

Abstract:

With the development of urban construction, lots of deep foundation pits have come forth continuously. As a new support structure for foundation pit, sheet piles is used in-situ due to its rigidity of pile body, but the mechanism of pile-soil interaction of sheet piles is still unclear. In order to study the bending moment behavior of sheet piles under different excavation situations and surcharge loading, the special device was designed and a series of model tests were conducted to investigate the effects of sheet piles retaining structure. The result indicates that sheet piles bending moment increases with excavations and loadings, but decreases after reaching 30 cm. bending moments are different in different positions, the deformation and moment in middle pile is the largest. Pile bending moment increases when piles spacing increases, for attenuating the pile group effect, pile-soil interaction of sheet piles can be used effectively when piles spacing is 5cm, and the supporting effect is ensured.
