Numerical analysis of offshore monopile foundations in layered clay

Applied Ocean Research
Monopiles are often embedded in layered soil profiles, where stratification significantly influences their lateral load response. However, much of the existing literature and proposed methodologies predominately focus on uniform soil profiles which is ...

A unified "p-y+M-θ " model for laterally loaded piles considering rigidities of various piles

Yantu gongcheng xuebao
The large-diameter monopiles account for over 70% in construction of offshore wind turbines in China. The current p-y curve design method is primarily suitable for the small-diameter flexible piles.
