摘　　要：为研究黏性土土层含水率对混凝土扩盘桩抗拔性能的影响,通过模型试验,研究不同含水率情况下,混凝土扩盘桩抗拔承载力及土体破坏状态的变化情况,利用ANSYS有限元软件进行模拟分析,并对分析结果进行比较。结果表明:黏性土层含水率对桩的抗拔承载力有较大的影响,承载力随含水率的提高而降低。In order to study the effect of moisture content of clay layer on the uplift failure of concrete expanded-plate（ CEP） pile,the effect of moisture content on CEP pile＇s uplift bearing capacity and soil failure mode were studied by model test. ANSYS simulation analysis was conducted and its results were compared,the results showed that the moisture content of the clay layer had a great influence on the bearing capacity of the pile,and the bearing capacity decreased with the increase of the moisture content.
