The Impact of Plant Root Systems on Stability of Mine Ecological Slope
The safety and stability of the slope planting Cynodondactylon(L.)Pers.,IndigoferakirilowiiMaxim.exPalib and Ulmuspumila L.undering the natural and rainstorm conditions were assessed using the finite element software Midas SoilWorks.The results indicated that the root systems of the 3 plant species had varying degrees of improvement on the safety and stability of mining slopes under various conditions.The degree of impact was closely related to the number of roots and the range action of roots on the slope soil.The combination of deep and shallow roots had the best effect.However,with the deepening of plant roots,the safety and stability coefficients of the slope were increased,and the horizontal displacement of the slope was also increased.Therefore,in the actual design,the comprehensive analysis and verification of the reliability of the slope should be combined with the safety and stability coefficients,stress and deformation to select the best design scheme.
