摘要：

The driving course of jacked pile in sand was simulated numerically based on the centrifuge principle and theory of particle flow code program. The changing properties of pile tip and pile lateral resistance for flat pile, 120° pointed pile and 60° pointed pile are analyzed respectively, which reveals the varying laws of its development. The results show that there existed critical depth of pile tip resistance. The largest of pile tip resistance among the three piles was the flat pile. The least was the 60° pile. The pile tip resistance was increasing with the increasing of driving speed, which its varying law was not entirely consistent at different depth. The lateral resistance of pile was gradually decreasing with the increasing of driving depth at the same position, and the lateral resistance of pile upside is zero or negative value. The lateral resistance of pile was increasing gradually along the depth direction at same driving depth.
