The invention discloses a test method for identifying the flowing and crushing mechanism of a discrete material under the action of an external load, which comprises the following steps: applying a load to discrete particles placed in a clamp, after the loading is finished, firstly acquiring an image about the top damage condition of the discrete particles in the clamp, and then measuring the height of the discrete particles, so as to identify the flowing and crushing mechanism of the discrete material. The granular particles are averagely divided into a plurality of layers according to the height, and the number of the layers is the same as that of the loaded granular particles; the crushed discrete particles are sequentially taken out in a layered mode, the discrete particles need to be prevented from being crushed again when taken out, and an image containing the crushing condition of the current layer is obtained every time one layer is taken out; each layer of the taken-out discrete particles is manually
