用动光弹性法研究材料引入的分配层对应力波传播的影响

A Dynamic Photoelastic Analysis for the Effect of Different Cushion Layers on Stress Wave Propagation in Structure

本文用动态光弹性模拟试验分析方法,观察和分析研究了材料不同的分配层对应力波在结构中传播的影响,比较分析了冲击荷载产生的应力波在洞室结构顶部的传播及相互过程,得到指定点处的应力—时间关系曲线,为结构震塌机理的进一步的研究和防护结构的改进提供参考。

The effect of different cushion layers on the stress were propagation in structure were investigated by dynamic photoelastic method.The propagation and interaction of stress waves in structure were compared under shock load, and stress vs time curves at appointed points were obtained. The experimental results can provide reference for further research on structural spllation and for improvement of protective construction.
