摘要
模型材料满足相似条件是振动台模型试验的基础。目前研究者都是通过大量的配比试验研制出满足相似条件的模型材料,而大量模型材料的力学试验表明,衬砌模型的结构还需要优化,围岩模拟材料要具有容重大、泊松比基本满足各类结构的要求、抗压强度和弹性模量较低、力学性能稳定、可以重复使用等特点。文章对振动台围岩和衬砌模型相似材料研究现状进行了探析。
The model materials meet the conditions of similarity is the basis of the shaking table model test. Now researchers developed satisfactory and similar condition of model material through a large number of matching test. A large number of model material mechanics experiment show that lining model of structure optimization, surrounding rock simulation material to big bulk densities, poisson＇s ratio of basic meeting the requirements of all kinds of structure, low comprehensive strength and elastic modulus, stable mechanical properties, repeatable, etc. This paper explores on shaking table model similar material research status of surrounding rock and lining.
