Microbially induced calcite precipitation (MICP) offers potential for the development of innovative and environmental friendly techniques for soil improvement. The main purpose of this study is deepening the understanding of bio-geochemical processes involved in MICP by means of numerical modelling. In this paper a coupled bio-geochemo-hydraulic model considering multispecies bio-reactive transport is presented. Generally, this model is based on the theory of porous media, continuum mechanics and solved by finite element method (FEM). Utilizing this model a numerical case study is performed. It is estimated that this model is able to predict a rational bio-geochemical behavior of MICP. Besides, sensitivity analysis regarding the relevant model parameters has been performed to identify key factors in the MICP processes.
