ON DESIGN OF VERTICAL SLOPES REINFORCED BY SOIL-NAILS

Based on soil plasticity and limit analysis theory, togther with tensile and shear forces of soil-nails considered, a designing method of vertical slopes reinforced by soil-nails is proposed under reasonable value of energy safety factor. The corresponding designing results of reinforced slopes coincide with engineering practice. The designing method proposed in the paper can also be applied to steep slopes reinforced by soil-nails.
