Abstract

The load distribution and deflection of large diameter monopile is investigated by lateral load transfer method (p-y curve). Special attention is given to the p-y characteristics using three-dimensional finite element analysis. A series of numerical studies are conducted on clay and sandy soil to determine the influence factors of monopile design. Based on the results, the modulus of subgrade reaction (K) and the ultimate soil resistance (pu) increase linearly with an increase in pile diameter, while pile-toe conditions exert no significant influence on the p-y characteristics. Moreover, it is also found that for flexible piles the effect of pile diameter on K is more significant than for rigid piles.
