摘　　要：为研究软弱破碎油页岩巷道蠕变变形特性及变化规律,根据地质力学模型试验相似原理及油页岩岩石物理力学参数,确定以硅胶粉和河砂为骨料,以正十四烷、石膏为胶结剂,通过相似材料配比及相似材料试件基本力学参数、蠕变参数测试,得到骨胶比为1∶0.4、骨料比为5∶5的相似材料,与岩石蠕变力学特性具有一致性,基本满足软弱破碎油页岩蠕变相似模型要求的材料配比。上述结果为开展油页岩地下开采巷道运营期的变形、破坏相似材料模型试验打下了坚实的基础。In order to study the creep deformation characteristics and variation of roadway made of weak and broken oil shale, according to geomechanics model experiment similarity principle and oil shale rock physical and mechanical parameters, taking silicon powder and river sand as aggregate, taking n-tetradecane and gypsum as cementing agent, through the similar material proportioning and its basic mechanical parameter and creep parameter testing, a similar material was obtained with aggregate-cementing agent ratio 1 ： 0.4 and aggregate ratio 5 ： 5 respectively. This similar material is consistent with rock creep mechanical characteristics, and basically meets the demands of similar model material proportioning for weak and broken oil shale creep study. Above results lay a solid foundation for the development of similar material model experiment of deformation and failure of oil shale underground mining tunnel, which is in operation.
