This paper investigates the use of global sensitivity analysis during the development of
metamodels for back-analysis of geotechnical problems. Variance-based global sensitivity analysis
was combined with Particle swarm optimization algorithm and POD-ERBF metamodel to backcalculate
the hypothetic (synthetic) problem of anchor-supported excavation. PLAXIS 2D FE code
was used for numerical simulations. The results of the back analysis for different sets of model
parameters were compared to emphasize the importance of global sensitivity analysis before
performing the back analysis and the recommendations for the robust modeling of presented
geotechnical problem were given.
