Embodiment Construction
[0032] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments; specific structural limitations.
[0033] like Figure 1 to Figure 2 Shown: This embodiment provides a test system for simulating rainfall-induced failure of a reverse-order grain accumulation, including an accumulation model 1, a measurement system and a rainfall simulation device.
[0034] The stacked body model 1 is made of quartz sand and is positioned in the model groove 10, and the stacked body model 1 is layered from top to bottom by being separated by colored spacer strips 9; the stacked body model 1 For example, it can be built into a slope surface structure as required; the accumulation body model 1 can be built by using angular quartz sand with a particle size range of 0.1 to 32 mm as a material; at the same time, pr...
