Development of a Coupled BCHM-Model for Numerical Investigations of MICP treatment of Soil

Bearbeitung:Dr.-Ing. Xuerui Wang; Prof. Dr.-Ing. Udo Nackenhorst
Laufzeit:2020-2022
Förderung durch:DFG (German Research Foundation)

Microbially induced calcite precipitation (MICP) provides a potential for the development of a sustainable technique to improve the engineering properties of soil. As a consequence of the complex biochemical and hydro-mechanical (BCHM) interactions induced by MICP, permeability in the soil can be significantly reduced, and the mechanical stiffness and strength of the soil can be notably improved. The goal of this project is to gain a better understanding of the complex BCHM interactions involved in MICP through numerical analysis. This project will focus on the investigation of the mechanical constitutive behaviour of the MICP treated soil and the development of a fully coupled BCHM model.
