摘要:: 在分析总结近几年岩土工程物理模拟试验中常用的岩质相似材料研究现状的基础上,采用重晶石粉、石英砂、石膏、甘油配制振动台模型试验相似材料,通过不同配比的材料力学试验,考虑相似材料的含水率,分析研究了各种材料含量以及含水率变化对相似材料物理力学性质的影响规律,发现含水率对材料的抗压强度、粘聚力、弹性模量、摩擦角有较大影响,根据试验结果最终确定了振动台试验相似材料配比。试验结果证明,该相似材料力学指标稳定,能很好地满足相似材料的选材要求,便于一次性浇注较大尺寸规模的模型试件,适用于大型振动台等物理模拟试验。

Abstract:: On the basis of analyzing and summarizing the research status of similar materials of rock which were usually used in physical simulation experiments of geological engineering in recent years, using the similar materials of shaking table model tests compounded by barite powder, quartz sand , gypsum and glycerol, through mechanical test of different proportion of materials, and considering the water content of similar materials, the contents of all kinds of materials and the regularity of the influence of the water content changing on the physical and mechanical properties of similar materials were studies and analyzed. It was found that water content had great influence on the compressive strength, cohesion, elastic modulus and friction angle of materials. According to the result, the proportion of similar material in shaking table model test was fixed finally. It was proved by the test that the mechanical index of this kind of material was stale, could meet the needs of the choice requirements of similar materials, convenient for pouring relatively largescale model specimen once only. It applies to physical simulation experiments like largescale shaking table model test.
