In order to study the slope protection effect of plant roots, the parameters of soil samples collected in the field and oleander roots drawn from laboratory tests were put in the numerical simulation of rooted soil with a 3D finite element software ABAQUS to identify the effects of root morphology and distribution density on the slope soil displacement. The results showed that planting oleander can effectively reduce the displacement of the topsoil and protect the slope. The more the number of fibrous roots and the greater the distribution density, the less the displacement of the slope soil. With the growing plant density, the displacement decreased significantly as well. The results of numerical simulation provided a theoretical basis for the application of plant roots in slope protection engineering.
