摘　　要：以香根草根系为研究对象,将根系与土壤视为一整体,探讨在不同含根量下根土复合体抗剪强度指标的变化规律,应用室内三轴试验的方法研究了根土复合体的应力-应变关系及强度特性,并且比较了素土与含根土的强度特性,以及它们的变形破坏模式。With vetiver grass roots as the research object,root and the soil as a whole.The change of shear strength indexes of root-soil composite with the quantity of grassroots plantees in the soil samples was investigated.Laboratory triaxial tests were carried out in order to understand the stress-strain relationship and strength property of root-soil composite.The strength property and the failure modes of soil and root-soil composite were contrasted.
