Sandy soil structure test model

The utility model relates to a sandy soil structure test model, which belongs to the technical field of geotechnical engineering and comprises a counter-force mechanism, a static force loading mechanism, a model stacking mechanism, a data acquisition system and a shooting system. The counter-force mechanism comprises a counter-force cross beam and a cross beam height adjusting controller, the static force loading mechanism comprises a speed reducer, a lifter and a loading plate, the model stacking mechanism comprises a sandy soil particle simulation material and a model frame, and the data acquisition system comprises a pressure sensor and a data acquisition instrument. According to the test model, the change of particles in the structure can be visually observed, the displacement of the particles in the sandy soil structure at each moment is tested, the movement rule of the particles in the structure and the damage mechanism of the sandy soil structure are determined, and the requirement for operators is low
