Study on the Uplift Bearing Capacity of Rock-Socketed Piles
In this study, we conducted three-dimensional finite element analysis of the uplift bearing capacity of rock-socketed piles using ABAQUS FE software. After verifying the reliability of the numerical model, a large number of numerical calculations were performed by varying parameters including rock-socketed depth, pile length, pile diameter, and elastic modulus of the pile shaft to analyze their effect on the uplift bearing capacity. The results show that the relationship between uplift load and displacement of a rock-socketed pile consists of three stages: an elastic deformation stage, an elastoplastic deformation stage, and a plastic failure stage. The uplift bearing capacity increases with increasing rock-socketed depth, pile length, and pile diameter. As rock-socketed depth increases, the proportion of frictional resistance to uplift load increases nonlinearly. With increasing of elastic modulus of the pile shaft, the ultimate uplift bearing capacity of a rock-socketed pile increases, whereas the pile-top displacement decreases.
