Geosynthetic reinforced soil Structures-A critical appraisal of design and construction

The awareness of geosynthetics in the country has begun around the year 1985. Soon after, the first Geosynthetic Reinforced Soil Retaining Wall has been built. Since then many hundreds of such structures have been constructed in the country in a variety of ground situations. After reviewing the basic design mechanism of reinforcing with geosynthetics, a critical appraisal of the prevailing design and construction practices in the country through the use of British, FHWA, NMCA Codes of Practice has been attempted. The importance of adequate geotechnical investigation and various aspects of construction, such as the type of reinforced fill soil to be used, and connection strength have been highlighted. Typical case histories have been presented.
