    When it comes to using reinforcements to grant better mechanical performance to soils, geosynthetics, one of the newest groups of building materials, have become mandatory in almost all works of infrastructure, draining applications, waterproofing, paving, erosion control and soil reinforcement.



    This volume presents the basic mechanisms associated with soil-reinforcement interaction and a rational design method for reinforced soil-retaining structures. Concepts are described with didactic and theoretical rigor, fulfilling the practical needs of engineers involved in the design, construction and inspection of reinforced soil structures.



    Soil –Reinforcement Interaction



    Concepts of reinforced soil, Characteristics of geosynthetics for reinforcement, Soil behavior and Influence factors on reinforcement tension.





    Analysis and design













    External Stability, Internal Stability, Determination of maximum reinforcement tension, Determination of the location of reinforcement maximum tension point, Pullout analysis, Reinforcement and facing connections, Design Resistance of reinforcements, Stress increments due to surcharge loadings, Lateral displacement and strain prediction and Case studies







    Constructive Aspects









    Type of reinforcement, Type of facing and construction procedure, Arrangement of reinforcements, Drainage system, Backfill material, Quality control and constructive tolerances, Guardrails







    Design Example









    Soil and wall characteristics, External stability analysis, Internal stability analysis, Comparison of methods for reinforcement tension determination and Wall final arrangement
