Physical modelling on unsaturated soils using centrifuge
Résumé
The behavior of geotechnical structures located near the soil surface is highly influenced by unsaturated soil conditions. Some researches about the potentialities of centrifuge modeling of geotechnical problems involving unsaturated soils are presented, with a focus on scaling laws, soil preparation, instrumentation and atmospheric actuators. Finally some ideas to improve the practice of centrifuge modeling with unsaturated soils are presented.
