摘　　要：为了不同的土质中变截面DX桩的承载特性,比较不同土质对桩抗压承载力的影响。首先介绍了ABAQUS模拟分析时土单元和桩身单元。然后通过使用ABAQUS有限元软件对同种土质条件下的变截面DX桩和等截面桩的承载过程做数值模拟分析,并与模型试验数据进行对比研究,研究结果表明数值模拟结果具有较高可靠性。In order to study the bearing characteristics of DX piles with variable cross-section in different soils,the influence of different soils on the compressive bearing capacity of DX piles was compared.Firstly,the soil element and pile element of ABAQUS were introduced.Then the finite element software ABAQUS was used to simulate the bearing process of DX pile with variable cross-section and DX pile with equal cross-section under the same soil condition.The results show that the numerical simulation is of high reliability.
