Using the theoretical analysis results for the piles in soils undergoing lateral movement and the numerical simulation based on the finite element method
the sheltering effect of previously driven piles on the soil displacements in soft soils in pile driving engineering is discussed. The research shows that the sheltering effect of previously driven piles on the total lateral soil displacement is little. Different shear stiffness factors of the interface elements are used to analyze the influence of time interval between later and previously driven piles on the sheltering effect of previously driven piles. The sheltering effect of previously driven piles on ground heave is contributed mainly to the horizontal block to the soil movement and the restraining of soil heave by the large shaft friction for the short and long time interval
