Abstract
The lateral load response of a monopile is often modelled by p-y curves. However, the traditional formulation of p-y curves is unable to describe the behavior of liquefied soil. This paper presents a numerical investigation of how to develop p-y curves for monopiles installed in liquefiable soil. A monopile is modelled in the 3D finite element software package PLAXIS 3D, where a soil model able to capture liquefied soil behavior is applied. The numerical results are used to extract relevant data to assess liquefaction in the soil. Based on this information, p-y curves are generated for the liquefied soil.
