中文摘要:
      研究了橡胶树根表面与土体之间的摩阻效应,推导出树根抗拉拔力的公式,并估测橡胶树根表面与土体的摩擦系数为0.172~0.222,根据土体的固结压缩程度和根-土界面的摩阻力成正相关的线性关系,设计橡胶树根-土界面摩阻效应试验.试验结果表明,根部直径和树根埋深与抗拉拔力呈线性关系,土体固结时间和抗拉拔力呈正相关对数函数关系,在相对较短的时间内,固结载荷与抗拉拔力成线性关系.
英文摘要:
      When the root soil complex under external load, developed between root and soil movement or the trend. The faulting is resisted by interface friction, which made the root under tension and produce tensile resistance, thus affect the shear strength of the rubber root-soil composite. Because of that, we design the test of friction effects of the interface of rubber tree roots-soil to explore tree root. Experiment showed that the root diameter and root depth are presented linear relationship with the tensile resistance, the consolidation time of soil is presented linear relationship with the tensile resistance with a logarithmic function, and in a short time, consolidation load is applied for a linear relationship with tensile resistance. Through the analysis, we also derived the root resistance formula of tensile resistance and friction coefficient on the surface of the rubber tree roots. At the same time, the degree of consolidation of soil compression and friction resistance of roots and soil interface presents a linear relationship of positive correlation.
