摘　　要：为探索植物根系与土体间相互作用的特性,基于土力学、复合材料力学的基本理论,分析了土壤-植物根系复合材料的性能,借鉴于矩形模型理论的分析方法,并在该模型基础上作了一些简化和假设,详细推导出了土壤-植物根系复合体的弹性模量的理论计算公式,推导过程中综合考虑了应力、应变同时存在的情况,该求解值能够真实完整地代表实际值,以此来推动土壤-植物根系复合体工程特性的深入研究,为工程绿化、植被护坡、边坡稳定等方面的应用提供理论基础。In order to probe into the frictional characteristic between plant root and soft,material character of the soft-plant root complex was analyzed based on the basic theory of soil mechanics and mechanics of composite materials. Benefiting from the analyzing method of the rectangle model theory and some predigestions and assumptions on this model,the calculating formulas of elastic modulus of the soil-plant root complex were established in detail.Through considering a comprehensive process of stress and strain at the same time,the solution can represent actual value,which promotes the intensive study on the character of the soil-plant root complex.It would also be helpful to promote theoretical foundation for the aspects of engineering virescence,slope protection by vegetation,slope stabilization etc.
