摘　　要：相似模拟研究是一种重要的科学研究手段,用石膏、大白粉以及河砂作为相似材料,依据相似理论可以满足岩石的抗拉强度和单轴抗压强度,很难满足某些岩石的容重。用锯末和铁粉来调节相似材料的容重,依据相似原理使相似材料满足岩石的抗拉强度与单轴抗压强度,同时满足岩石的容重。Similar simulation research is an important means of scientifiC research, plaster, big white powder and river sand as similar material, on the basis of the similarity theory can satisfy the tensile strength of rock and uniaxial compressive strength, it is difficult to meet some of the rock density. With sawdust and iron powder to adjust the density of similar material, based on the principle that similar material meet the tensile strength of the rock and the uniaxial compressive strength, at the same time satisfy the bulk density of the rock.

关 键 词：相似模拟 抗拉强度 砂胶比 骨料
