Analysis of Wave Loads on Pile-Group Foundation

Abstract:

The grouping pile foundation is widely used in the construction of bridge over sea and its scale of construction is generally dominated by the wave force on the pile groups. Because of the presence of the slab, not only the incident wave but also the diffraction wave should be considered in calculating wave loads on pile groups. The diffraction from a submerged circular cylinder representing the slab was taken as an example, and wave loads on piles in the diffraction wave field were calculated by using Morison formula. Results show that the effect of slab decreases with the increase of incident wave number. Changing laws of different piles in the pile-group foundation varied with the submerged depth. Wave loads at the meeting-wave side of slab is larger than the back side of that. And the presence of slab caused the deflexion of inline force. The grouping piles coefficient can be taken as 0.7.
