摘　　要：讨论了大面积柔性荷载下考虑桩土共同作用的桩基础沉降问题,提出了大面积柔性荷载下的桩基础沉降计算方法,并将理论计算结果与某工程算例的沉降进行了对比,表明理论方法的可靠性与有效性。Details of the settlement study on the pile foundation bearing the large-area-flexible load are discussed taking into account the interaction of piles and soil. A method to calculate the settlement of the pile foundation bearing the negative friction under this condition is proposed. Analysis results for an engineering example show that the proposed method is feasible.

关 键 词：桩土共同作用 柔性荷载 负摩阻力 沉降
