摘  要:
[目的]分析植物根系在土壤中的力学性质,证明植物能提高坡面的稳定性。[方法]以胡枝子、五节芒为研究对象,测定植物根系的抗拉强度。[结果]根系的存在确实对土体抗剪强度有所提高;当根系的总长度恒定时,根系粗细是影响抗拉拔力的主要因素。[结论]植物根系可以提高土体的抗剪强度和抗拉拔能力,增强边坡的稳定性。

摘  要:
[Objective]The mechanical properties of plant roots were analyzed in the soil, demonstrating that plants can improve the stability of the slope.[Method]Taking Miscanthus floridulus, Lespedeza bicolor as test object,pull-out strength of plant root was determined.[Result]The presence of roots did improve the shear strength of the soil. When the total length of the root system was constant, the root thickness was the main factor affecting the pull-out resistance.[Conclusion]Plant roots can improve the shear strength and pull-out resistance of the soil and enhance the stability of the slope.
