    Patent name: Field test method and device for mechanical properties of falling ball geomaterials

    Patent No:ZL200810087044.7


    Patent No:ZL200510021852.X

    Patent name: Method for improving the accuracy of portable deflection meter (H-FWD) test using acceleration sensor




    The tunnel irrigation technology is based on the Hertz impact theory and the Vesic cavity expansion theory. It can test the deformation modulus during compression and rebound, and then calculate the corresponding deformation index (material deformation modulus and strength index) of the rock mass material.



    Test principle and method


    Test method for deformation characteristics of geomaterials based on Hertz impact theory;
    Test method for strength characteristics of geomaterials based on Vesic cavity expansion theory;
    It can quickly detect the on-site mechanical properties of a wide range of materials from soft clay, sand, gravel to cement stabilized soil and asphalt concrete, and has obvious advantages compared with the existing PFWD/EVD.
