1黏土中静压沉桩离心模型显示文摘采用西澳大学室内鼓轮式离心机,在预先固结的高岭黏土中开展不同离心力场(50g,125g及250g,g为重力加速度)条件下的模型压桩试验、T-bar试验和静力触探试验,分析了模型桩在贯入过程、静置稳定过程中桩身径向应力(σr)的变化规律,并对后期桩体拉伸载荷阶段的径向应力变化值(Δσr)及桩侧摩阻力变化情况行了探讨,揭示了在不同超固结比(OCRs)黏土中静压桩侧摩阻力的演变特性.在此基础上,通过两种经验公式方法对桩侧摩承载力进行了预测计算和对比分析.研究结果表明:沉桩过程中桩端相对高度(h/B)对桩身径向应力的发展变化有很大的影响,桩身不同位置(h/B)的总径向应力对同一贯入深度而言,存在桩侧径向应力退化现象;基于静力触探试验提出的经验方法,能有效考虑静力触探锥端阻力(qt)和桩端相对高度(h/B)因素的影响,将其应用于黏土沉桩时桩侧摩阻力的预测,可取得与试验实测结果较吻合的结果.研究成果对软土地区静压桩施工与承载力设计具有一定的工程指导意义.李雨浓 Barry M Lehane 刘清秉 2018工程科学学报2018,40,3:23
2双层高岭黏土中沉桩特性模型试验显示文摘为了揭示黏土中静压沉桩的宏观力学特性,采用西澳大学的梁式离心机压桩系统,通过在双层高岭黏土中进行一系列1g重力场情况下的T-bar触探测试试验、静压沉桩试验、桩拉伸试验和压缩试验,对比分析了T-bar分别在均质软质黏土和双层黏土中随贯入深度变化测得的不排水剪切强度的特性;研究了桩体在贯入过程中沉桩阻力、桩端阻力以及桩侧摩阻力的发展规律;并对桩身径向总应力在沉桩过程中的变化规律进行了探讨;此外,还揭示了不同桩型沉桩终压力与桩承载力之间的关系。结果表明:在黏土中沉桩时,桩侧摩阻力在整个沉桩阻力中发挥主要的作用;对于同一土层而言,当桩超过土层分界面以下2 D(D为桩径)范围后,桩端阻力并不受相邻土层性质的影响;随着压桩后时间的推移,桩侧摩阻力对承载力的时效影响较桩端阻力大。李雨浓 Lehane B M 2018吉林大学学报(地球科学版)2018,48,6:14
