| 摘 要： | 试验研究和理论分析表明,柔性桩存在有效桩长.考虑刚性基础对桩顶部桩-土相对位移的限制,假定桩侧摩阻力为双折线三角形分布,根据桩-土协调变形,推导出复合地基中柔性桩的有效桩长,并在此基础上提出将柔性桩复合地基压缩层分为三层进行沉降计算.通过实例验证该方法是有效且可行的.

| Abstract: | Experimental study and theoretical analysis indicate that effective length of flexible piles exists.Considering the resistance of rigid foundation to the relative displacement between piles and soils,assuming the frictional resistance distributed as triangle form,and based on the pile-soil compatible deformation,the effective length of piles is deduced.And the settlement of flexible piles composite foundation is divided into three sections to be calculated.Comparing the method introduced in this paper with ... |
