Slope Stability Analysis of Railway Embankments Considering the Effects of Vegetation and Capillarity
Publication: Experimental and Applied Modeling of Unsaturated Soils
Abstract
It is well known that vegetation influences slope stability in following ways: (1) By mechanical reinforcement from the plant roots; (2) by increasing in soil suction or reduction of pore water pressure; (3) by surcharge from the weight of trees; and (4) by"wind throwing." The main beneficial effect includes root reinforcement. Roots increase the shear strength of soil primarily by transferring shear stresses that develop in the soil matrix into tensile resistance in the roots via interface friction along the imbedded roots.
