摘　　要：在现场试验的基础上,对预应力高强度混凝土管桩单桩承载力荷载传递特性进行了三维数值模拟分析。模拟结果表明:在其他条件相同的情况下,预应力高强度混凝土管桩单桩极限承载力、轴力和桩身侧摩阻力在一定范围内随桩长和桩径的增加而增大。The characters of PHSC pipe pile is introduced simply in this paper, and its bearing capacity and load transfer behavior are analyzed by 3-D numerical simulation. The results indicate that when other parameters are the same, the ultimate bearing capacity,axial load and skin friction of single PHSC pipe pile increase with the increases of length and diameter of piles.
