Model test research on bearing capacity of vertical reinforced sand foundation

The model test in combination with the non-target digital photography deformation measure technology was carried out to study the bearing capacity, soil-pressure distribution, reinforcement mechanism and deformation pattern of vertical reinforced foundation. The results shows that the length of vertical reinforcement and the distance of vertical reinforcement to foundation have obvious influence on the bearing capacity and soil-pressure distribution, the main mechanism of vertical reinforcement is confinement and obstruction, and the deformation pattern is dependent on the location and length of vertical reinforcement.
