A Semi-Analysis Solution for the Dynamic Compliance of a Horizontal Pile Embedded in a Layered Poroelastic Half-Space

Based on the second kind of Fredholm integral equations describing the dynamic interaction between the layered half space and the pile, the dynamic compliance of a horizontal pile subjected to a top harmonic lateral load is constructed. The proposed methodology is validated by comparing results of this paper with some existing results. Numerical results show that for a three-layered half space, the presence of a softer middle layer in the layered half space will enhance the compliance for the pile significantly, while a stiffer middle layer will make the dynamic compliance of the pile decrease considerably.
