Numerical Simulation of Deformation Pattern to Pile Raft Foundation

Abstract:

ABAQUS is used to study the load-settlement characteristic and soil displacement field of the pile raft foundation. Numerical results are compared to the outputs from model test. The study results show that good consistency is obtained from the comparison of results between numerical simulation and model tests. Small pile space will weaken the single pile bearing capacity. The compress region is mainly centralized in the soil beneath the pile tip to the 3b space pile raft foundation, which presents a massive deep foundation failure pattern. As the increase of pile space, the compress region under cap shifts upward. The displacement influence depth of 6b space pile foundation is smaller than 3b space pile raft foundation, and it is destroyed by the lateral squeeze of the soil around piles.
