摘　　要：通过阐述位移协调法及计算步骤,结合实例,对大面积堆载下桩基负摩阻力进行了计算,并对计算结果得出的曲线进行了分析比较,反映了大面积堆载时桩身负摩阻力的一般规律,从而对消减或避免负摩阻力有一定的实际意义。According to the description on the displacement coordination method and the calculation procedures, combining with project, the paper gets calculation on the negative friction of the pile foundation under the large area loading, as well as the analysis and comparison on the curve got from the calculation results, reflects general law of pile negative friction under large area loading, thus having certain significance on decreasing or avoiding negative friction.
