Geotextile Encased Columns (GEC): Load Capacity, Geotextile Selection and Pre-Design Graphs
Embankments over soft subsoils supported by piles or stone columns have several advantages over the classical unsupported embankment foundation when compared in terms of bearing capacity, serviceability, and duration of construction. In extremely soft soil conditions, lateral support can be problematic for stone columns. An alternative system, which can both provide the required lateral support and increase bearing capacity, is the "Geosynthetic Encased Columns" (GECs). This system includes a high-modulus, creep resistant geotextile encasement called Ringtrac® that confines the compacted sand or gravel column thereby providing constructability and bearing capacity even in extremely soft soil. The following describes the design principles, technologies and procedures developed over the past ten years and the importance of the geotextile encasement's tensile modulus. Also presented are graphs showing the influence of different factors on settlement. They could be also used in preliminary designs for orientation and proper encasement selection.
