摘　　要：首次用动态光弹性试验模拟研究了地质断层对应力波的影响及相互作用 ,比较分析了冲击荷载作用下水平和 30°方向的裂缝的动态响应 ,得到指定点处的条纹级数 -时间关系曲线图 ,研究了结构物顶部震塌的机理 ,为防护结构的改进提供了参考。It is the first time to simulate stress wave effect and interaction of faultage by using dynamic photoelasticity, and dynamic response of horizontal and 30 degree crack were compared under shock load, and stress-time curves of appointed point were obtained. Experimental results can provide reference for further research on spallation of structural top and improvement on protective construction.
