The mechanics of steep reinforced soil slopes are considered to seek improvements in the simplified design charts published by Jewell et al (1984). A description of the equilibrium in a steep reinforced slope is given which clearly identifies the mechanics governing the maximum required reinforcement forces for equilibrium, and the required reinforcement length. Two independent limit equilibrium analyses are used to derive revised design charts, which are presented in the paper, and to identify some conservatisms in the existing charts. The influence of reinforcement bond is clearly identified and a bond allowance is introduced for chart design. Savings in reinforcement quantity of the order 20% to 30% can be achieved for slopes designed using the revised charts. (Author/TRRL)
