植物根系对边坡的加固作用模拟分析

Analogue Analysis of Roots′ Reinforcement to the Slope Stability

采用有限元方法对植物根系加固边坡的作用规律进行了模拟分析,随着根的长度增加,边坡稳定性安全系数也逐渐提高,当根的长度超过3 m时,长度增长将不再导致边坡稳定性安全系数的增加;根的数量对边坡稳定性的影响与根长相同,在一定范围内,根的数量越多,边坡稳定性安全系数越高;根对边坡的加固作用的发挥也与根的位置有很大的关系。根的长度、数量都是随着时间的推移而增长的,所以根的固坡效果也随着时间的推移而加强。

In this paper, the author uses the method of FEM analogue analysis to explore the law of roots working on the slope stability. After the analogue analysis, the law was derived that the more the roots are, the more stable the slope is; and the longer the roots are, the more stable the slope is, to certain extent. On all accounts, the slope with roots reinforcement will be more and more stable with the passing of time.
