摘　　要：边坡表面经常受到波浪冲击、地表水径流和地下水渗流等因素作用,形成表面侵蚀和浅层滑坡现象。植物根系减小边坡表面水流冲刷和地下水渗流、增加土体强度,具有明显浅层护坡效果。随着植物根系含量增大,根系土强度增大。植物根系土边坡的稳定性分析可采用类似加筋土边坡的分析方法。Slope surface is always under the action of wave impact, surface water runoff and ground water seepage and other factors, thus surface erosion and shallow landslide is formed. The root system of plant can reduce water scouring on slope surface and ground water seepage and increase the strength of soil mass, which has outstanding effect on shallow slope protection, and the strength of root soil is increased with root magnitude. The stability of soil slope with roots system of plant can be analyzed by the method similar to that for reinforced soil slope.
