Transient analysis of monopiles embedded in layered saturated soils under vertical excitations
Abstract This paper investigates the transient dynamic response of vertical loaded monopiles embedded in layered saturated soils. Firstly, the piles are modeled as the one-dimensional rods, which are solved by the finite element method (FEM). Then the analytical layer-element solutions of layered saturated soils are used as the kernel functions of the boundary element method (BEM), and the boundary integral equation of the soils are further acquired. By introducing the pile-soil interface conditions, the transient response of the pile-soil system is obtained with the aid of the FEM-BEM coupled method. The proposed method is verified by comparing the results with those in existing literature and ABAQUS. Finally, parametric studies are conducted to determine the effects of the length-diameter ratio, pile-soil modulus ratio, stratification and permeability.
