Geomechanical model test simulated deteriorated rock mass similar material and proportion determination method
The invention discloses a geomechanical model test simulated deteriorated rock mass similar material and a proportion determination method. The similar material comprises aggregate, a cementing agentand a blender, a gypsum mixed material is selected, barite powder and quartz sand are adopted as the aggregate, gypsum is adopted as the cementing agent, an aqueous solution is adopted as the blender,the raw materials of different mass ratios are fully mixed and tamped, and the similar material with the physical and mechanical properties required by a physical simulation test and the water softening effect is obtained. The similar material disclosed by the invention is relatively large in adjustable range of physical and mechanical parameters, and can be used for effectively simulating the characteristics of deteriorated rock mass and structural surface of the reservoir bank slope in water. The similar material is simple in preparation method, wide in raw material source, low in cost, non-toxic, harmless and particularly suitable for being widely used in model tests of reservoir bank degradation slopes.
