A Review of Research Progress on Uplift Pile

Based on VOSviewer software, this paper conducted bibliometrics on the relevant literature of uplift pile research, revealed the annual number of publications, international cooperation, and keyword co-occurrence in this field. On this basis, it systematically reviewed the research progress on uplift piles in three aspects: experimental studies, numerical simulations, and theoretical analyses. The experimental studies include field tests and laboratory model tests, with a focus on the uplift resistance of different types of piles under various geological conditions. Regarding numerical simulations, the applications of the finite element method, finite difference method, and discrete element method in the force analysis of uplift piles were introduced. The theoretical research summarizes the calculation methods for the bearing capacity of uplift piles and the research results on their deformation and failure modes. The research results show that many issues remain to be resolved regarding the mechanical responses and long-term performance of uplift piles under complex geological conditions and multi - load interactions. It is urgently necessary to further explore these issues to refine the design theories, improve the construction techniques, and provide more reliable technical support for practical engineering.
