| 摘 要： | 对植被边坡中根系固土的力学效应进行了分析,将深粗根系视为锚杆,将浅细根系和周围的土体看作均匀复合介质,建立了有限元计算模型,以一个算例分析了根土复合介质的强度参数对边坡整体稳定性的影响。

| Abstract: | Mechanism of soil reinforcement by plant roots is analyzed. The finite element model is proposed thinking plant roots and herbaceous root-soil as anchors and uniform composite materials respectively. Effects of strength parameters of soil-roots composite on the stability of slope are analyzed with a computational example. |

| Keywords: | plant roots apparent cohesion finite element method |
