摘要
结合实际工程,采用ABAQUS数值计算软件,对天津滨海吹填场地中不同初始固结度下的单桩承载性状进行了有限元模拟,并对不同桩顶荷载作用下的桩侧摩阻力进行了对比,得出沉降量和桩侧摩阻力与不同初始固结度之间的对应关系,同时还分析了初始固结度不变时单桩的承载性状.分析结果为进一步研究天津滨海吹填土中桩的承载与变形形状提供了一定的理论参考.
Based on an actual project in Tianjin Binhai dredger fill ground,the finite element simulation is carried out on the bearing characteristics of single pile in different initial degree of consolidation by using ABAQUS numerical recipes software,and then the contrast of pile side resistance in various working load on pile top is proceed.This paper finds out the corresponding relationships among settlement,pile side resistance and initial degree of consolidation.Meanwhile this paper also analyzes the bearing characteristics of single pile in the same initial degree of consolidation.The research results will provide a theoretical reference for the further investigation of the bearing and deformation characteristics of piles in Tianjin Binhai dredger fill ground.
