- 論文の詳細を見る
A new limit equilibrium analysis for assessing the stability of a reinforced embankment on soft clay against rotational undrained failure is presented. The analysis considers strain compatibility along the slip surface to deduce the tension mobilized in extensible reinforcement at collapse condition, and models strain softening of soils along the slip surface. The load extension responses of the reinforcement can be dependent on confinement by soils. Non-uniform increase in undrained cohesion during construction can be accounted for. The analysis yields a 'Safety Factor Curve' instead of a unique value for safety factor. A parametric study for illustrating the relevance of the proposed analysis is reported.
