Abstract:In this paper, a numerical model of the vertical revetment sheet pile is established by using the finite element software ABAQUS, the effects of elastic modulus of the sheet pile, wave height and wavelength on the horizontal displacement of the pile body are studied.The results show that the vertical revetment sheet pile moves to the side of water, the displacement of the pile increases firstly and then decreases with the depth of pile increasing.The displacement is small below the depth of 13m. The elastic modulus of pile has little effect on the displacement of the pile.Under the same conditions, as the elastic modulus of pile increases, the horizontal displacement of pile from the pile top to a depth of 13m gradually decreases, the elastic modulus has little influence on the horizontal displacement of sheet pile below the depth of 13m.Wave height and wavelength have great influence on the horizontal displacement of the pile at the depth range from 0m to 13m, and they have little influence on the horizontal displacement of sheet pile below the depth of 13m.Under the same conditions, with increasing of wave height, the depth at the maximum displacement point of pile increases gradually, the horizontal displacement of the pile from the pile top to the depth of 13m decreases gradually.With increasing of wavelength, the horizontal displacement of the pile from pile top to the depth of 13m decreases gradually.
