Mathematic model descripting bearing behaviors of super-length piles on sea

Based on field test data of piles in the foundation cross-sea bridges, this paper has a study on the mathematic model descripting the bearing characteristics of pile, that is pile top load versus pile top settlement curve, which reflect the bearing behaviors of super-length cast-in-place pile and super-length steel pipe pile by the same mathematic model. It is found that, the effect of fitting with the mathematic model proposed in this paper is good, the mathematic model is appropriate to describe these curves, and it can provide new method for the estimation and calculation of pile top load, pile top settlement of super-length pile on sea.
