N2 - In this paper, aiming at the problem of bearing mechanism in granular material, material, we design a granular material photoelastic device with multi-way loading material, we design a granular material photoelastic device with multi-way loading to study the micro mechanical structure of the granular system. In this device, we not only design a vertical compression and horizontal shear system, but also develop an automatic data acquisition system to collect boundary force data and photoelastical image during the loading process. The grating ruler is used to collect the displacement while the force sensor is applied to record the reaction force. Based on the LABVIEW software we can make the boundary force data and photoelastical image visual. Photography system is used to grab real-time image of the force chain in the granular system during the loading process, the direct observation of the bearing construction and distribution of the internal force chain in the granular system is realized by the use of the photography system. According to the result contrast analysis between physical experiment and numerical simulations, we verify the validity and accuracy of the granular material photoelastic device.
