摘要
依据国内外岩土工程中大体积岩石模型相似材料的研究现状及材料的优缺点,选取水泥、石膏、河砂以及水进行岩石大模型相似材料研究。通过改变砂胶比、水固比、石膏占胶体比因素,获取水泥砂浆试件的表观密度、单轴抗压强度、试件压力曲线及变化规律。结果表明,水泥砂浆是一种比较理想的大体积岩石模型相似材料,值得深入探究。
Based on analyzing the research status of similar material of massive rock model and the advantages and disadvantages of massive rock model of the geotechnical engineering at home and abroad. The cement,gypsum,river and and water are used to conduct the study of the similar material of massive rock model.The apparent density,uniaxial compressive strength and specimen pressure curve are obtained and thiers change regularities are summarized by changing the parameters of sand cement ratio,water solid ratio and gypsum colloid ratio.The results show that the cement mortar is a ideal similar material of mas-sive rock model,therefore,it worth conducting further study.
