摘要
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 时间关系曲线图和应力 时间关系曲线图,研究了结构物顶部震塌的机理,试验结论可为防护结构的改进提供参考。
The experiments to simulate the stress wave effect and interaction of geology faultage have been down by using dynamic photoelasticity. The dynamic response of horizontal and 30 degree crack are compared under shock load. The stress-time curves and stress-time curves at appointed point are obtained. The spallation mechanism of the structure is studied. Experimental results could be a reference for improvement on protective construction.
