摘　　要：通过对海南儋州区域某水工工程钢管桩的竖向静载试验及桩侧摩阻力试验数据进行研究,分析超长大直径钢管桩在该区域深厚沉积层的竖向承载性状和荷载传递机理,积累该区域的深厚沉积层土层侧阻力系数样本数量,为该区域后续工程或相似区域工程提供经验与参考。Based on the test data of vertical static load test and pile side friction resistance test,the authors analyze the characteristics of vertical bearing capacity and load transfer mechanism of the super-length and largediameter steel pipe piles in the deep sediments,at an area which in a Hainan port,and collect sample numbers of friction coefficients in the deep sediments of the area,in hope to provide reference for projects in similar situation.

关 键 词：超长大直径钢管桩 承载力性状 荷载传递
