Model approach for the coupled hydraulic-mechanical system [modified after Maßmann (2009)]. The simulation of the hydraulic process is based on the conservation of the liquid mass which states an interaction between pressure, fluid velocity and saturation. The mechanical process is based on the conservation of linear momentum, which incorporates interactions between stresses, strains and displacements. A coupling of both processes is implemented due to the classical Terzaghi effective stress approach, as well as a linear swelling/shrinkage model
