摘　　要：针对中国西北地区浅埋隔水层破裂规律的物理相似模拟研究需要,根据固液耦合相似理论,以细河沙、膨润土为骨料,石膏、固体石蜡为胶结材料,甲基硅油为添加剂,经过大量配比实验,研制出873系列固液耦合相似材料。通过单轴抗压实验以及渗透性实验对873系列材料的单轴抗压强度和渗透系数进行了测定。测试结果表明,该相似材料具有低强度、遇水泥化的弱胶结性、良好的隔水性能等特点。To investigate the fracture law of aquiclude in north-western China shallow seam,a new kind of solid-fluid coupling similar material(i.e.,873series) was proposed using the solid-fluid coupling similarity theory. The873 series were structured by fine sand and bentonite,cemented by gypsum and paraffin and regulated by methyl silicone oil. Its characteristics, such as low permeability,weak compressive strength and cementation,are consistent with the properties of aquiclude in north-western China shallow seam.
