The paper is referring to the geotechnical centrifuge modelling that is used to prove the gabion facing wall stability. The gabion reinforcement wall is 15.3 meters tall and 17 meters length. The centrifuge model was speed up to 50 g and 75 g, and hadn't failure. The test results show that the largest settlements under 75 g speed was about 2.25 meters vertically and mainly in the gabion wall and just behind the gabion section. The largest settlements under 50 g speed was about 1.07 meter vertically and 1.8 meters horizontally. The value of the settlement increases with the shortness of the reinforcement. The value of the settlement decreases with the reduction of the gabion spacing in the wall facing. Reinforced gabion retaining wall can work safely. Nevertheless, mechanical and deformation behaviors need to be studied for wide applying in a practical engineering.

W artykule przedstawiono zastosowanie centrifuge - wirówki przeciążeniowej w literaturze geotechnicznej. Zaprezentowano realny przykład zachowania się ściany zbudowanej od frontu z gabionu, którą poddano wymuszonemu przeciążeniu silą 50 g i 75 g. Badania zostały przeprowadzone na zlecenie The Collin Group w Laboratorium Carleton, w Departamencie Civil Engineering and Engineering Mechanics Faculty, University of Columbia. Badania w wirówce przeciążeniowej wykazały, że ściana o początkowej wysokości 15,3 m i długości 17 m została stabilna przy przeciążeniu 75 g. Największe pionowe osiadanie wyniosło 1,07 m, a poziome 1,82 m.
