Biological Considerations in Geotechnical Engineering

Abstract: The understanding of soil behavior during the last 300 years has centered on mechanical principles, geological processes, and later on, mineralogy and the relevance of colloidal chemistry. More recently, research in biology and earth science has enabled important advances in understanding the crucial involvement of microorganisms in the evolution of the earth, their ubiquitous presence in near surface soils and rocks, and their participation in mediating and facilitating most geochemical reactions. Yet, the ef… Show more

“…As bacteria have a typical size of 0.5-3 lm, it is hard to be transported through silty or clayey soils. Bioclogging could occur when bacteria are adsorbed or strained by the solid grains, resulting a heterogeneous CaCO 3 precipitation in the soil (Mitchell and Santamarina 2005). Previous research of biogrouting investigated the improvement of coarse grain soils (Whiffin 2004;De Jong et al 2006;Whiffin et al 2007;Ivanov and Chu 2008;Harkes et al 2010;Van Paassen et al 2009.…”

“…Alternative metabolisms and bacteria for large scale applications in biomineralization of CaCO 3 have also been investigated by the group (van Paassen et al, 2010). Indeed, it has been 85 commented that the type of bacteria utilized is one of the major considerations and potential limitations in large scale geotechnical operations (Mitchell and Santamarina, 2005). Therefore, the search for new bacteria by which to achieve viable levels of MICP is important for optimizing the protocol best suited (in terms of performance, economics and environmental impact) for marketing in green industry (Cheng and Cord-Ruwisch 2012;Patel 2015;van Paassen et al, 2010).…”

“…Although ignored for centuries with respect to geotechnical behaviour, microbes are ubiquitous in soils at surprisingly high concentrations, almost regardless of saturation, mineralogy, pH, and other environmental factors. Near the ground surface, more than 10 12 microbes exist per kilogram of soil (Mitchell & Santamarina, 2005). At depths typical in geotechnical systems (e.g.…”
