【摘要】 通过对现场灰岩岩性指标进行统计分析,结合相似原理,选择水泥、石膏和砂等原料模拟现场的灰岩特性,在室内进行了大量的小试样配方试验,得到了几种能有效模拟灰岩岩性的配方。各配方的力学性能表明该水泥石膏模拟材料能较好地模拟现场灰岩特征,基本满足相似模拟材料的要求。更多还原

【Abstract】 Through making statistics of analysis for the limestone’s index on-the -spot, combining similar principle, we select the materials such as cement, plas ter and sand to imitate the limestone. After being carried out plenty of little sampling prescription experiments in the laboratory, we have gotten some kinds t o imitate the prescription of limestone efficiently. It can imitate the limeston e feature on-the-spot better , and satisfy the requirement of similar simulated material basically if the mechanics performance of each prescription shows this cement plaster mold to draft material.更多还原
