摘　　要：本文讨论软岩地基中基桩极限承载力问题。在圆形荷载作用下 ,根据地基中任意一点的应力大小 ,以及桩顶的沉降量 ,求解基桩的极限荷载。同时根据试桩结果 ,对照理论计算 。This paper intends to illustrate the ultimate bearing capacity of pile in soft foundation.Under circular load,the bearing capacity of pile is obtained by stress at different positions and settlement of pile butt.According to the result of test piling,the cause of error is analyzed based on the theoretical formulas.
