  • In-situ test system and method for subgrade dynamic resilient modulus
    Patent number: 11913186
    Abstract: A loading module includes a test vehicle, a servo cylinder is mounted on the test vehicle, a piston rod of the servo cylinder is connected with a bearing plate acting on a subgrade surface, an annular loading plate is disposed around the bearing plate, and the loading plate is connected, through a force transmission rod, with a bearing tray on which a counterweight block is placed; a data collecting module includes a second high precision displacement sensor and a plurality of first high precision displacement sensors; a data processing module includes a computer, the computer is connected with a signal input end of the servo cylinder, an output end of the first high precision displacement sensor and an output end of the second high precision displacement sensor respectively, and performs inverse calculation for a dynamic resilient modulus value of a subgrade using a software.
