Yes, there is a source for a geocell-reinforced embankment relying on a controlled modulus column. The source is a technical paper published in the journal Transportation Infrastructure Geotechnology, titled “Analysis of Geocell-Reinforced Stone Column-Supported Embankment Considering Soil-Structure Interaction” by M. P. Vibhoosha, Anjana Bhasi, and Sitaram Nayak1. The paper presents a three-dimensional coupled analysis of a geocell-reinforced stone column-supported embankment, considering the interactions between the geocell, the infill material, and the surrounding soil. The paper also compares the performance of the geocell-reinforced stone column-supported embankment with that of an ordinary stone column-supported embankment and a geosynthetic-reinforced stone column-supported embankment. The paper can be accessed online from the SpringerLink website2 or downloaded as a PDF file3.
