Model similar material for simulating slope dangerous rock mass and preparation method of material
The invention discloses a model similar material for simulating slope dangerous rock mass and a preparation method of the material, each raw material has unique functions, barite powder is used as a weighting material, semi-refined paraffin is used as a binder, No.32 hydraulic engine oil is used as a lubricant, and ultralight clay is used as an additive. The finally mixed similar material has the properties of high weight, low strength and low elastic modulus, and meets the mechanical properties of the dangerous rock mass under natural conditions; by changing the ratio of the raw materials, the compressive strength and the deformation modulus of the similar material can be changed under the condition of ensuring the required volume weight, and both the semi-refined paraffin and the No.32 hydraulic engine oil in the raw materials have the effect of changing the mechanical properties of the material; change of the compressive strength and the deformation modulus of the similar material in a large range can be controlled by slightly changing the ratio of the raw materials; and in the preparation process, only the raw materials need to be dried and dewatered, other steps are carried out at room temperature, the preparation process is simple, the preparation efficiency is high, and the cost is relatively low.
本发明公开了一种用于模拟边坡危岩体的模型相似材料及其制备方法，每种原料都具有独特的功能，重晶石粉作为加重料，半精炼石蜡作为粘结剂，32号液压机油作为润滑剂，超轻黏土作为添加剂，最终混合而成的相似材料具有高重度、低强度、低弹模的性质，符合自然条件下的危岩体的力学性能；通过改变原料的配比，便可在保证所需容重的条件下，改变相似材料的抗压强度和变形模量，原料中的半精炼石蜡和32号液压机油都具有改变材料力学性质的作用，并且较小的原料配比的改变即可控制相似材料的抗压强度和变形模量在较大范围内的变化；在制备过程中，仅需要对原料进行烘干除水的处理，其他的步骤都是在室温下进行，制备过程简单、制备效率高、成本较低。
