双荚决明不同弯曲程度单根抗拉变形特性
Tensile deformation characteristics of single root with different bending degree of Cassia bicapsularis
[目的]在西南喀斯特地区,植物根系大多以弯曲形态存在,而以往研究多选取均匀顺直的根系,对于弯曲根抗拉特性还不得而知,弯曲根力学特性的研究有助于揭示根系固土机制。[方法]为探究不同弯曲程度根系固土的力学性能,揭示其固土护坡机理,以五年生边坡绿化树种双荚决明为研究对象,采用单根拉伸试验,探讨弯曲根抗拉变形特性。[结果]1)双荚决明不同弯曲程度根系的抗拉力和抗拉强度均表现为顺直根>微弯曲根>弯曲根,极限延伸率为弯曲根(29.26%)>…查看全部>>
[Objective]In the southwest Karst areas,most of the plant roots exist in the form of bending.The previous studies mostly selected uniform and straight root systems,but the tensile characteristics of bending roots are unknown.The mechanical properties of bending roots could helps to reveal the root soil solidification mechanism.[Method]The 5-year-old slope greening tree species Cassia bicapsularis was used to explore the mechanical properties of solid soil wi…查看全部>>
