      摘要
    • 摘要: 依据天津某液化天然气接收站码头工程,采用ABAQUS有限元软件研究了码头全直桩基础在波浪和车辆双向循环荷载作用下的受力特性,讨论了循环周期对基桩受力特性的影响。结果表明：在竖向和水平向双向循环荷载作用下,基桩受力重新分布,桩身轴力逐渐变大,侧摩阻力减小,其中中排桩桩身轴力增加幅度最大;基桩侧摩阻力变化主要集中在1/3桩长以上范围;循环周期对基桩受荷分布产生较大影响,随着循环周期的变大,基桩受荷分布逐渐调整,前、后排桩桩身轴力逐渐变大,中排桩桩身轴力减小,排桩侧摩阻力均减小,当荷载循环周期达到一定值时,排桩的桩身轴力、侧摩阻力不再变化,趋于稳定。
      Abstract: Based on a liquefied natural gas terminal wharf project in Tianjin, the finite element software ABAQUS is used to study the mechanical characteristics of pile groups of wharf foundation under lateral and vertical cyclic loadings, and the influence of cyclic period of lateral and vertical loadings is discussed. The results indicate that under the lateral and vertical cyclic loadings, the stress of piles redistributes, the shaft force of piles increases, and the side resistance decreases. The increase amplitude of shaft force row piles is the largest. The range of side resistance is mainly concentrated in the area of more than 1/3 of pile length. The cyclic period has great influence on the stress redistribution: with change of the cyclic period, load distribution of piles adjustes gradually, the shaft forces of front and back row piles increase, and the shaft forces and side resistances of the middle row piles decrease. When the cyclic period reaches a certain value, the shaft forces and side resistances of piles no longer change and tend to a steady state.
