The layered shear soil box is widely used in shaking table tests, as it effectively minimizes boundary effects and allows for soil shear deformation(Li et al., 2023a; Lei et al., 2020). Additionally, 5 cm thick plates are placed on both sides of the model box to eliminate the influence of boundary waves generated by water vibrations.
