草本、灌木植物及木本植物的侧根与岩土体相互作用是类似的,都对边坡岩土体起到摩擦加筋的作用,使边坡土体成为土与根的复合材料,在浅层边坡岩土的加固中起到重要作用,从而提高土体强度,达到使边坡浅层土体稳定的目的.但是目前的研究仍然停留在定性地分析根与土体的作用关系上,本文试图在定量分析摩擦型根和岩土相互作用原理方面做些探索性的工作,通过对草本植物的根系(包括木本植物的侧根系)与岩土体的相互作用的研究分析,建立了摩擦型根-土力学作用模型,运用云南松野外实验结果验证了模型预测的正确性.力学模型的建立为定量地分析植物根系与土体的相互关系提供了重要的理论指导,具有一定应用价值.
The lateral roots of herbs, shrubs and woody plants are similar to the interaction between rock and soil, and they all play the role of friction and reinforcement for the slope rock and soil so that the slope soil becomes the composite material of soil and root. Layer slope rock and soil reinforcement plays an important role in improving the strength of soil so as to achieve the purpose of stabilizing the slope shallow soil.However, the current study still remain in the qualitative analysis of the role of roots and soil, This paper attempts to do some exploratory work in the quantitative analysis of the interaction principle of frictional root and soil, and through the research and analysis of the interaction between the root system of herbaceous plants (including the lateral root system of woody plants) and rock and soil, The friction type root-soil mechanics model, the correctness of the model prediction is verified by the experimental results of the yunnan pine.The establishment of the mechanical model provides important theoretical guidance for the quantitative analysis of the relationship between plant root and soil, and has certain application value .
