Abstract

Abstract: Regarding the root soil composite as an integrated organism of soil and roots, this thesis selects a typical slope plant nerium indicum as the research object, and utilizes the non-linear finite numerical analytical method to study the effects of different roots distribution density and lateral roots amount on the stability of slope surface soil under the condition of the rainfall and slope surface runoff erosions. The results showed that the existence of roots contributes substantially to the enhancement of the integral stiffness of the surface soil in a rainfall situation. It is indicated that the displacement of the slope surface and rainfall erosion on the surface soil are decreasing with the increase of distribution density and lateral roots amount, so that the surface stability can be reinforced.
