公路隧道衬砌模型材料的研究

Study on the Lining Model Material of Highway Tunnel

模型材料的研究主要是根据相似理论,寻找一种力学参数与实际工程材料相似的模型材料。通过改变模型材料各组成成分的配比,分析各种配比对模型材料各力学参数的影响,同时分析单种材料对模型试件物理性质的影响,根据试验所得变化规律,确定一组较佳配比的模型材料用于模拟公路隧道衬砌。

Based on similarity theory,the study is to investigate a certain model material which has physical and mechanical parameters similar to engineering cases.Through changing the proportion of each component of model material,analyzes the effect on the mechanical parameters,meanwhile explores effect of a single kind of material on the physical property of model specimen.On the basis of the variation of experiments,determinates a practical ratio of components for the simulation of highway tunnel lining.
