| 摘 要： | 为研究灌木根系植入土质边坡浅层不同位置与深度的加筋锚固作用，建立了根系植入边坡的二维平面模型，并分析了在边坡土体自重作用下的根系主根轴力分布与塑性破坏时的坡体内位移分布。模拟计算结果表明:植入土质边坡坡脚附近的灌木根系可以对边坡浅层土体起到锚固作用；灌木根系植入土质边坡可以降低边坡土体塑性破坏时的坡体位移，使边坡稳定性有所提高，可为植被护坡工程浅表层加固效果评价提供一定依据。

Analysis on Finite Element Simulation of the Shrub Roots Planted Soil Slopes |
| |
| Abstract: | In order to study the anchoring effect at different locations and depths of the shrub roots planted shallow soil slopes, the planar model of root planted slopes was established, and the taproot axial force under the dead weight of the slope soil and the displacement distribution of the slope in the plastic failure are analyzed. The simulation results show that the roots near the toe of the slope can anchor the shallow soil of the slope; the roots can reduce the displacement of the soil during the plastic failure of the slope and increase the stability of the slope. The research results can provide a certain basis for the evaluation of shallow surface reinforcement effect of vegetation slope protection engineering. |
