Upscaling of Bio-mediated Soil Improvement

PDF Version Also Available for Download.

Description

As demand for soil improvement continues to increase, new, sustainable, and innocuous methods are needed to alter the mechanical properties of soils. Recent research has demonstrated the potential of bio-mediated soil improvement for geotechnical applications (DeJong et al. 2006, Whiffin et al. 2007). Upscaling the bio-mediated treatment process for in situ implementation presents a number of challenges to be addressed, including soil and pore fluid interactions, bioaugmentation versus biostimulation of microbial communities, controlled distribution of mediated calcite precipitation, and permanence of the cementation. Current studies are utilizing large-scale laboratory experiments, non-destructive geophysical measurements, and modeling, to develop an optimized and ... continued below
