摘要
在研究了国内外近几十年岩土工程中常用的相似材料的研究现状,并分析了它们优缺点的基础上.通过试验测定不同水灰比和橡胶粉取代率时,改性水泥砂浆的表观密度、抗压强度、弹性模量和劈拉强度等物理力学性能的变化情况,总结这些物理参数随橡胶粉取代率、水灰比的变化规律,获得一种新型岩石相似材料.结果证明,这种新型岩石相似材料能很好地满足相似材料的选材要求,是一种比较理想的岩石相似材料,值得在其他模型试验中推广.
Based on the introduction of research status of similar materials commonly used in recent decades years at home and abroad, and advantages and shortcomings of these similar materials were analyzed. The physical properties of modified tubber powder cement mortar, including apparent density, uniaxial compressive strength, elastic modulus and splitting tensile strength , were studied. Variation of the physical parameters with replacement rate of rubber powder and water cement ratio was summarized, and a new rock similar material was produced. The results showed that the new rock similar material can well satisfy the requirements of similar material, and it was an ideal rock similar material and worth to he popularized in other model tests.
