摘要：
Geosynthetic reinforced embankments can fail before the ultimate tensile strength of the reinforcement is mobilized. For the purpose of embankment design, engineers must often rely on experience when selecting a reinforcement strain for analysis using limit equilibrium methods or resort to complicated numerical methods such as those based on the finite element method. This paper presents a simple procedure for estimating the undrained stability of geosynthetic reinforced embankments founded on soft clayey soils where the shear strength increases with depth. Finite element results are summarized in a design chart for establishing geosynthetic reinforcement strains suitable for design. The procedure is illustrated using worked examples and tested against a well documented case history. (C) 2003 Elsevier Science Ltd. All rights reserved.
