The development history of computational methods for vertical uplift capacity of horizontal anchor plates was reviewed.

Meso-structure characterization of sand was studied on pile-bucket foundation bearing uplift load.

With the increase of important-large project and development of engineering construction in ocean, the research on foundation under uplift loading and development of new type foundation attract more attention.

Numerical simulation for bearing performance of uniform-section pile under uplift loading;

Particle flow code numerical simulation of extended foundation under the action of uplift loading;

According to the result of PDF2D which was used to simulate pile - bucket foundation bearing uplift loading, this article analyses the process of the behavior of soil during the uplift loading, and sketches the rupture of particle of PDF2D.

The action point of uplift force plays a dominant role in the distribution of friction resistance along uplift piles,and thus it is a key factor in the analysis of the loaddisplacement relationship of uplift piles.

Through numerical method,uplift force of the headed stud in concrete steel truss composite girder was analyzed under various conditions for the reference in designing.
