Finite Element Analysis of the Effect of Core Pile in Combined Composite Foundation
Combined composite foundation has been widely used in actual projects, but its working behaviors need to be studied further. By establishing finite element model, the effect of the core pile was researched. Analysis shows that, the diameter and the length of core pile affect the bearing capacity of combined composite foundation significantly. There is an optimal value of the length and the diameter of core pile, which can make the foundation generate maximum carrying capacity. With the increase of core pile length, the depth of neutral point increased.
