Abstract
This paper investigates the bearing capacity and consolidation characteristics of PHC pile foundation through numerical simulation method. The numerical simulation results greatly shows the process of field static load test and the soil deformation characteristic around the pile, and the ultimate bearing capacity calculated by finite element method has a good agreement with the measured value. The numerical simulation method is used to study the consolidation behavior of composite foundation in one year after bearing load. The excess pore pressure dissipation regular, displacement of pile side soil, and pile stress distribution are systematically studied by numerical simulation method. The result shows that the modified Cam-clay model can greatly simulate the mucky soil consolidation characteristic especially the creep properties. And the consolidation settlement also has great agreement with the real value. This study proves the feasibility of the numerical simulation method in the study of the bearing capacity and consolidation of the pile foundation.
