摘　　要：以某工程案例为基础,将锚固岩质边坡大型振动台试验作为载体,来进行模型相似材料配比研究工作。主要针对水泥砂浆和岩石进行相似材料配比试验,试验选择甘油、石英砂、重晶石、石膏等物质作为主要材料,将相似理论为依据,通过正交设计法来规划试验方案,利用浇筑灌浆方式来制作样本。通过室内试验操作来取得相似材料的主要物理力学数据,如粘聚力、内摩擦角、抗拉强度、抗压强度等,再采用直观曲线图和极差分析法对相似材料来分析正交试验结果,从而选择合理的配比来制作锚固体模型,确保整个拉拔试验顺利进行。Based on an engineering case,this paper takes the large-scale shaking table test of anchored rock slope as the carrier to study the proportion of materials similar to the model.The proportion test of similar materials is mainly carried out for cement mortar and rock.Glycerol,quartz sand,barite,gypsum and other substances are selected as the main materials.Based on the similarity theory,the test scheme is planned through the orthogonal design method,and the sample is made by pouring and grouting.The main physical and mechanical data of similar materials,such as cohesion,internal friction angle,tensile strength and compressive strength,are obtained through indoor test operation,and then the orthogonal test results of similar materials are analyzed by intuitive curve diagram and range analysis method,so as to select a reasonable ratio to make the anchor model to ensure the smooth progress of the whole drawing test.Therefore,the problems existing in the actual project can be found and the function of advance prediction can be achieved.
