Bio- and Chemo- Mechanical Processes in Geotechnical Engineering

In recent years, substantial advances have been made in understanding the coupling between chemical and biological processes and mechanical and hydraulic behaviours in soils and rocks. At the same time, experimentation and modelling capabilities have progressed significantly, allowing effective design of geotechnical applications. The need for such analyses arises, for example, in chemical and biological soil improvement; nuclear, hazardous and municipal waste containment; petroleum and natural gas extraction; methane hydrate exploitation; CO2 sequestration; and assessment of pavement durability. The seventeenth Gotechnique Symposium in Print took place at the Institution of Civil Engineers on 3 June 2013 and sought to address the new challenges that are emerging from the interactions between multi-physical phenomena. These proceedings bring together the international research presented at the symposium and published across two issues of Gotechnique as well as additional subsequent research published in the journal. The papers selected for the symposium cover a wide range of geotechnical processes, including: Experimental analysis and constitutive modelling of the bio- and chemo-mechanical behaviour of geomaterials. Effects of changes in the pore water chemistry on soil and rock behaviour. Interactions between geometrical scales of diverse biological, chemical, physical and mechanical processes. Case studies of chemical and biological soil modifications. Applications of bio- and chemo-mechanical models in emerging technologies. Bio- and Chemo- Mechanical Processes in Geotechnical Engineering provides researchers and practitioners with a comprehensive introduction to the recent advances in the area and invaluable insight into the developments within this emerging field.
