The present work develops a theoretical model based on a rational mechanical model and the failure mechanism of anchor piles in the seabed, by which the failure mode and pullout capacity of anchor piles under inclined loading can be predicted in the soils with both cohesive and cohesionless properties. Experimental and numerical results are employed to validate the theoretical predictions. Parametric studies are performed to investigate the effects of different parameters on the failure mode and pullout capacity of anchor piles, to demonstrate the applicability and efficiency of the theoretical model and to gain further knowledge of the anchor properties. An analytical method is also proposed to evaluate the optimal position of the attachment point of anchor piles, and confirmed by relevant studies in either cohesive or cohesionless soils.
