摘　　要：介绍了大面积堆载条件下桩身微分方程的推导过程以及利用位移协调法确定大面积堆载条件下桩基负摩阻力的计算方法,最后有针对性地归纳出了减轻或消除负摩阻力的对策,以供参考。The paper introduces the reasoning process of the body-differential equation, and then introduces the calculating method that utilizing displacement harmony method to decide the burden-frictlon resistance of pile base under the condition of mass heap-loading. At last, it accordingly concludes the countermeasure to reduce or eliminate the burden-friction resistance, so as to provide a reference.

关 键 词：负摩阻力 位移协调法 承载力 强度
