Description: Miscellaneous Paper
Abstract: The introduction of high-strength geosynthetic materials has allowed for construction on heretofore impossible sites. Saturated, fine-grained soils with in-situ unconsolidated-undrained strengths as low as 1.0 kPa (20.8 lb/ft²) have been successfully used for embankment foundations using geotextiles or geogrids for direct ground support. When rapid consolidation of the subsoil is desirable, the procedure sometimes calls for insertion of strip (wick) drains and, for lateral flow, drainage geocomposites as well. This paper reviews and summarizes a number of soft-soil stabilization projects. Drawing from these experiences, a five-part design methodology is presented to select and size the various geosynthetic material properties involved. The paper closes with recommendations for future research and development.
