摘要
Microbially Induced Calcite Precipitation (MICP) is an innovative technique for soil grouting involving a bacterial reactive grout. This comprehensive research study is carried out to better understand and describe the coupled phenomena of multispecies reactive biogrout transport in a saturated, deformable soil. A unique predictive model of the behaviour of the porous media during biogrout injection is presented. The general field equations describing the system are derived from the macroscopical balance equations and constitutive equations. The set of field equations is numerically discretised. Finally, numerical examples are provided as a first step to validate the capabilities of the proposed model. (C) 2012 Elsevier Ltd. All rights reserved.
