چکیده مقاله
The interaction between plant roots and soil plays a crucial role in enhancing shear strength, particularly in erosion prone regions This study investigates silty clay soil reinforced with Nandina domestica, a shrub with a fibrous root system suitable for bioengineering applications A total of 72 direct shear tests were conducted on rooted and rootless soil at four depths 0 5, 5 10, 10 15, and 15 20 cm Soil shear plane images were processed to calculate the root area ratio RAR , defined as the ratio of root surface area to the total soil surface area Sensitivity analysis using the Morris method was employed to better understand the influence of soil depth, root weight density RWD , moisture content, and normal stress on soil reinforcement The results demonstrate that roots reduce soil shear displacement while increasing shear strength Finally, a data driven polynomial equation was proposed to describe the root soil reinforcement behavior
