摘要

草本植物根系使边坡土体浅层成为土体和根系的复合材料，它通过根土摩擦作用和根的抗拉作用，增强了根系土层的整体抗剪强度，但至今人们对草本植物根系对边坡岩土体的作用及效应的研究仍很少，亟待深入。通过对草本植物根系加固边坡的力学原理进行了全面的分析，不但提出了根土作用的力学模型，而且对边坡增加的抗剪强度和增加的边坡稳定性系数进行了定量计算。从而为草本植物生态护坡提供了理论依据。

Abstract

Since there are the root systems of herbaceous plant in the shallow layer of soil masses of slope

the shallow layer of slope becomes a compound materials made of soil masses and root system.Owing to friction action and tensile resistance action of roots

the shear strength of soil layer with root system is increased.And a comprehensive mechanical analysis of how herbaceous plants strengthen slope was carried out.Not only a mechanical model of interaction between root and soil

but also a quantitative calculation of increase of shear strength and stability coefficient of slope was put forward.As a result

the theoretical basis of herbaceous plant ecological slope protection was provided.
