Abstract

<p>Direct shear tests were made on soil specimens, including ten types of herbaceous roots for vegetation work. In addition, strength parameters (cohesion c and angle of shear resistance φ) were aging evaluated. In the second year, the ⊿c (c value increases) in ten types of herbaceous roots showed larger than those in the first year. In addition, eight also increased the ⊿φ (φ value increases) compared with those in the former year. The results showed that the seed and nodal roots increased the cohesion c of the slope surface soil. Furthermore, the binding force of the surface soil due to the development of lateral roots increased the angle of shear resistance φ. Therefore, the herbaceous roots of RCG, ChF and MF, whose strength parameters (⊿c and ⊿φ) increase over time, are worthy of consideration as herbaceous plants that can be applied to vegetation work as alternatives TF, an exotic species under industrial control.</p>
