Abstract

Abstract

Numerical simulation plays an important role in groundwater in-situ chemical remediation. Based on the physical and chemical reactions occurring in the remediation procedure, the relevant governing equations were analyzed, including soil equilibrium, continuity of fluid phases, and mass transport. Several common pieces of software for groundwater in-situ chemical remediation were introduced and compared. The effect of soil deformation on groundwater flow and mass transport was highlighted and the problems for current numerical simulation were discussed. Further development in numerical simulation of in-situ chemical remediation was proposed, including coupling among soil deformation, groundwater flow and mass transport, injection of remediation agents and resultant soil deformation and failure and change in permeability, as well as the effect of injection on soil mechanical properties.
