Vertical Dynamic Response of a Pile Embedded in Layered Transversely Isotropic Unsaturated Soils

This paper investigates the dynamic response of a pile embedded in layered transversely isotropic unsaturated soils subjected to a vertical external excitation. The quintessential Biot biphasic model for saturated media is replaced with a triphasic model for unsaturated media, which simulates more realistic terrestrial subsurface soil characteristics. With the aid of the boundary element method (BEM), the soil around the pile is divided into a...
