摘要
运用有限元法模拟林木根系与土体相互作用是林木根系固土机理研究的创新点。就林木根系与土体间相互作用的有限元数值模拟中存在的根土复合体的有限元离散化模型的建立、根土复合体各类型单元的本构模型的建立、根土复合体各单元本构模型参数的确定问题、造林边坡稳定性的评价问题等关键问题进行了探讨,并对今后的发展提出了建议。
The study on simulating root-soil interaction using finite element method is a novel point of root soil-reinforcement mechanism. This paper probed some questions existing in the finite element numerical analysis of root-soil interaction, such as the foundation of root-soil composite finite element discretization model and units constitutive model, the ascertain of root-soil composite units constitutive model parameters and the appraisement of afforested slope stability, then the suggestion on the development in the future was put forward.
