The invention discloses a multi-directional layered shearing model box capable of simulating saturated soil solidification, and belongs to the technical field of civil engineering. The model box comprises three parts of a lattice steel frame, a flexible model box body and a drainage system. The lattice steel frame includes two parts of a suspension bracket and an upper lattice beam frame; the upper lattice beam frame is put at the top end of the suspension bracket provided with multiple universal joints; the flexible model box body is formed by arranging multiple layers of layered structures manufactured by light rigid materials and with random shapes in parallel at equal intervals, and is suspended on the upper lattice beam frame; one layer of drainage system is laid at the bottom of the model box body; and a drainage pipe provided with multiple water ports is cast in a concrete layer at the bottom of the box. The model box greatly reduces the influence of vibration of other structures besides the box body on a model foundation in testing, can satisfy multi-dimensional seismic motion input requirements, fully considers solidification and drainage of saturated model foundation, and can effectively and truly simulate natural drainage and solidification of saturated soil.
