| 概要 |
Through laboratory-based testing, this study investigates the effect of Bermuda grass (Cynodon dactylon) roots on the shear strength of silty sand soil. Unreinforced soil and soil reinforced with ver...tically and horizontally oriented roots were subjected to direct shear tests under normal stresses of 22.5, 45, and 90 kPa. The results indicated that the internal friction angle was significantly enhanced by roots that were vertically aligned, while horizontally aligned roots contributed to increased cohesion. The tensile strength of the roots was also examined, and it was found that the tensile capacity of the roots in the lower sections was higher due to their smaller diameter. The substantial reinforcement potential of Bermuda grass was underscored by the experimental shear strength values, which surpassed theoretical predictions. Specifically, these results endorse the utilization of locally accessible vegetation as a sustainable and cost- effective soil stabilization method, particularly for the purpose of erosion control and slope protection. The study emphasizes the significance of root orientation in shaping soil behavior and suggests that additional research be conducted in field conditions and with a variety of soil types.続きを見る
