A DESIGN PROCEDURE FOR GEOTEXTILE-REINFORCED WALLS

The wide range of applications of geotextile-reinforced walls is noted, and includes temporary road embankments and permanent structures remedying slide problems and widening highways. They may be noise barriers or abutments for secondary bridges. Because of their flexibility, they can be constructed in areas where poor foundation material exists or areas susceptible to earthquakes. The problem of the internal stability of reinforced walls is discussed. The analytical approach to this problem is based on a limiting equilibrium analysis. The properties of materials is discussed including retained soil, backfill, and geotextiles. The discussion of internal stability covers composite structure, geotextile tensile resistance, and surcharge load.
