| 摘 要： | 植物根系的固土作用是通过影响土壤的应力、应变状态来实现的,然而根系在土壤介质中的受力复杂而多变,使得确定其加固能力非常复杂和艰难.为了深入研究植物根系在增强土壤抗剪强度中的作用机理,文中将植物根系和土壤看作复合体,采用直剪试验方法,研究了植物根系的分布密度对土壤抗剪强度的影响,进而建立了植物根系的"锚固"公式,为定量分析植物根系的固土作用奠定了基础. |

| Abstract: | Plant roots role of the reinforcement soil through affecting the soil's stress and strain state to realize,however roots in the soil of the medium by the complex and changing,strengthening its ability to make very complex and difficult. For an in depth study of plant roots in the soil shear strength enhancing the role of the mechanism,the paper will be seen plant roots and soil as composite, using direct shear test method,focusing on the distribution of plant root density on the shear strength of soil,then establishing the "anchor" formula,which can make quantitative analysis of the root soil plant role. |
| Keywords: | highway Eco-protection roots and soil composite root experiment-research |
