摘要
植物根系在坡面绿化与边坡稳定中发挥了重要的作用。笔者在总结多年来相关根系固土研究成果的基础上,分析了根系固土的概念和固土范围,以及根系固土的抗剪机理、抗拉拔机理、加筋理论等,总结了影响根系固土的关键因素及根系固土的数值模拟等方法。在此基础上,提出了目前国内外根系固土研究中存在的问题及根系固土力学机理研究方面的发展趋势。
Plant roots play an important role in slope vegetation and stability. Basis on the years of research, this paper first explored the concept and range of roots reinforcement on soil, and then systematically expounded shear mechanism, drawing mechanism, stiffened theory. Moreover, the related influence factors were summarized into two types and the nu-merical simulation were also reviewed. At last, this paper analyzed the shortcomings in current research and the forward further study in the future.
