Abstract
In this contribution an FE-algorithm for parameter identification of geometrically-linear fluid-saturated porous media is proposed, in which non-uniform distributions of the state variables such as stresses, strains and excess pore fluid pressure gradient are taken into account. Thereby, a least-squares functional consisting of experimental and simulated data is minimized, and where the simulated data are obtained with the FE-method. In order to improve the efficiency of the minimization process, a gradient-based optimization algorithm is applied, and therefore the corresponding sensitivity analysis is briefly explained. The performance of the strategy is demonstrated for a slope stability problem.
