摘　　要：利用有限元软件ABAQUS建立模型,用来测试桩承受轴向荷载时桩的承载性能.在达到满意的结果之后,该数值模型再用来分析在边载作用下桩的性能.基于这些数据,作出相应的图和表,预测中性面的位置以及在桩身上的摩阻力分布.A model was built with finite element software ABAMU~, wmcn was nr^t used to test bearing capacity of the pile subjected to axial load,when reaching a satisfac- tory result. This numerical model is used to analyze the performance of piles under side loads. Based on these data, the corresponding chart was made and the location of the neutral surface and the distribution of frictional resistance on the pile were predicted.

关 键 词：沉降 边载 粘土 摩阻力
