Investigation of key parameters and issues in simulating centrifuge model tests of a sheet-pile wall retaining a liquefiable soil deposit

Numerical simulations of centrifuge experiments examining a sheet-pile wall with liquefiable backfill are conducted and results compared against the experimental responses to evaluate numerical tools’ ability accurately predict seismic performance this geosystem. The platform FLAC constitutive model PM4Sand used for simulations, focus is placed on displacements. influence relative density (D R ) system’s response evaluated, together other parameters such as soil’s permeability construction method. consideration both mass-based CPT-based D estimates allows better prediction overall range permanent Other have moderate important effect estimated pre-shaking displacements but only minor end-of-shaking • modeling tests retained deposit from different research facilities performed part LEAP 2020. using 8.0 v3.1 sands. Overall, good agreement between measured predictions observed. Experimental enveloped by predictions. sand controls simulated
