Abstract: (4127 Views)
Stability of reinforced slopes is almost always carried out using limit equilibrium methods and controlled by the shear strengths of the slope materials and the extension force of reinforcements. According to limit equilibrium methods, the stability of slopes is assessed by dividing the whole failure wedge into several vertical elements. In order to determine the safety
factor of the reinforced slopes, a new approach is proposed based on the inclined slices method. According to this approach, a 4n formulation is introduced which uses fewer unknowns and a simpler formulation to calculate the extension forces of reinforcements and safety factors of the slopes. Additionally, moment and forces equilibrium in all slices are taken into account while the tensile force of each reinforcing element is independently calculated. Comparisons revealed differences at 5 to 10 percent level between analytical results obtained from this method and those of ReSSA software.
