  • Patent number: 12222330
    Abstract: A large-scale direct shear apparatus for direct shear test of multi-size cylindrical undisturbed soil samples, comprising an external framework, a sample shear box, a horizontal loading device, a vertical loading device, and a control system. The sample shear box is disposed within the external framework and includes an upper shear box, a lower shear box, and a base. The horizontal loading device includes a horizontal drive motor equipped with a load sensor, a horizontal mechanical loading mechanism, and an upper shear box connection structure. The horizontal drive motor is installed on one inner side of the external framework and contacts the lower shear box via the horizontal mechanical loading mechanism. The upper shear box connection structure is fixed to the other inner side of the external framework and contacts the upper shear box. The vertical loading device includes a vertical drive motor and a vertical mechanical loading mechanism.
