摘要: 相似模拟试验中砂的粒径对相似模型抗压强度的影响往往被忽略,从而导致相似材料的精确配比不易得到。通过配比试验,研究在其他条件相同的情况下,砂的粒径对相似模型强度的影响,试验结果表明相似试验中模型强度与砂的粒径负相关,粒径对模型强度影响程度与砂胶比正相关,对利用砂作为模型骨料的相似模拟试验有一定的参考作用。

Abstract: The influence of the sand particle size on the compressive strength of the analog model study is always ignored in analog simulations. This omission leads to the difficulty of finding the matching ratio of the model. The impact of the particle size of the sand on the compressive strength in the analog model studies with other factors remain unchanged. The results indicate compressive strength of the model is reversely related to the particle size of the sand. The impact of the particle size on the strength is proportional to the cementation of the sand material.
