摘要
相似材料强度特性直接影响物理相似模拟实验设计和边坡稳定性预测的可靠性和准确性。以水厂铁矿为依托,通过现场地质勘察、理论计算、调控介质配比组分和试验等方法,考虑岩体脆性和延性特点,开展了多介质复合相似材料强度试验及对比分析,揭示单轴压缩下相似材料应力累积与损伤演化规律和强度之间的内在关系,确定相似材料配比参数,为大型三维物理相似模拟实验提供了依据。
Strength properties of similar materials directly affect the reliability and accuracy for physical simulation experiment design and slope stability prediction.Taking Shuichang iron mine as engineering background,serveral methods including the field geology exploration,theoretical computation,regulation of materials proportion and experiment were applied.And the strength test of multi-media composite similar materials and comparative analysis were finished considering brittleness and ductility of intact rocks.Moreover,it is indicated that the regularity between strength and stress accumulation or damage characteristics of similar materials under uniaxial-compression.Finally,the parameters of similar materials＇ proportion was determined.Those will provide a basis for large scale three dimensional physical simulation experiments.
