The utility model relates to a testing device for a contact mechanical property experiment on coarse-grained soil, and the testing device comprises an upper clamping device and a lower clamping device, wherein the upper clamping device and the lower clamping device are arranged opposite to each other; the upper clamping device and the lower clamping device are same in structure, are respectively composed of a concave base, a square gasket, a clamping piece with an arc pit, and a fastening screw, and are used for fixing two granules and bearing the load of a loaded platform so as to realize normal and tangential contact tests on the two granules. By matching with the gaskets which are different in thickness, the clamping pieces and the fastening screws, the testing device can be used for testing the normal and tangential contact mechanical parameters of two granules which are same or different in diameter.
