摘要
论述了草本和灌木植物根系加筋土体、锚固土体、牵拉土体的力学效应,并结合国内外学者所采用的理论分析、模型试验、数值模拟等多种方法,系统评价了根系提高土体强度的力学效应及其对边坡稳定性的影响,并在此基础上指出了今后的研究方向。
The paper elaborates on the mechanical effects of reinforcing-soil,anchoring-soil and slant restraining-soil of grass roots and shrub roots.It systematically evaluates on the mechanical effects of plant roots in reinforcing the soil strength by using various methods of theoretical analysis,model tests and numerical simulation used by foreign and domestic scholars and puts forward the future research direction based on that.
