Embankments on Soft Ground and Ground Improvement

Conference:
GeoAsia 2012
December 13 -15, 2012

A review on the recent research and development on the use of geosynthetics for construction of embankment on soft ground and related ground improvement methods is given in this lecture. For embankment on soft ground, three commonly adopted methods: basal reinforcement using geosynthetics, consolidation using prefabricated vertical drains (PVDs), and geosynthetic-reinforced columns/pile supported embankment (GRCSE) system are briefly discussed. For ground improvement, only selected topics are elaborated. These are vacuum preloading, geosynthetic encased columns and geogrid enclosed stone columns, use of geotextile tube or mats for dike or embankment construction, and use of geosynthetics for construction over ultra-soft soil.
