摘要
基于Abaqus软件,建立桩土有限元模型研究了扩底桩在上拔荷载作用下的承载性状。结果表明:扩底桩达到抗拔极限承载力时,桩底与土体产生了分离,扩底桩抗拔承载时的桩身轴力在扩大头的上下出现突变,扩大头承受了桩的大部分荷载,塑性应变主要发生在扩大头附近的土体中。
Based on Abaqus software, the bearing properties of pile with enlarged base subject to uplift loading were studied by creating the finite element model of pile and soil. The results show that the bearing capacity of pile with enlarged base to the limit, a separate were produced between pile bottom and soil, the axial force of pile had mutations at the upper and lower of the enlarged head, the enlarged head could bear the most load of pile, the plastic strain occurred mainly in the soil near the enlarged head.
