摘　　要：在单相相似模拟材料研究基础上,用石蜡、沙子和油为骨料和胶结剂,按一定比例制作试件,并测试了其抗压强度及渗透性,得出与原始岩石抗压强度及渗透性相似的配比范围。结果表明,石蜡与沙子的比例增大,材料抗压强度增大;油量的变化,导致抗压强度下降的拐点位置的后移,消除了仅使用石蜡和沙子时,材料抗压强度变化强烈的不足,通过调整石蜡与沙子比例来控制材料的透气性。Based on the research of single-phase similar model materials,choosing paraffin,sand and oil as the aggregate and cementing agent to make triaxial test by a certain percentage,the research tests the compressive strength and it＇s permeability,and then comes out the ratio range which is similar to original rock compressive strength and permeability.Results show that with the continuous increase of the proportion of paraffin and sand,the compressive strength of materials increases;while test changes the amount of oil,the inflection point which caused the decrease of compressive strength keeps moving backward,this eliminates the weakness of compressive strength change of materials when the test simply uses paraffin and sand.The permeability of material is controlled by adjusting the ratio of paraffin and sand.
