A concrete‐cored gravel (CCG) column is composed of a precast concrete pile inserted at the center of sand or gravel materials. This technique has been experimentally adopted to support the soft soils in China. However, there has been limited investigation on the consolidation characteristics of a CCG column improved foundation under embankment loading. This study develops analytical solutions for...
A new soft ground improvement method is proposed combined with soil–cement columns and prefabricated vertical drains (PVDs) to increase the bearing capacity and to accelerate the consolidation process of soft soil. A series of centrifugal modeling tests is conducted on an embankment on a composite foundation, combined with soil–cement columns and PVDs. The effects of column spacing and column length...
