摘要
复合结构在抗动荷载方面具有明显的优势,它比一般的结构能够吸收更多的冲击能量。根据f 2.5 m爆炸模拟器上所做的实验结果和动力有限元方法对应力波的传播进行的计算,对应力波在有软回填层的地下复合圆形结构的介质中传播规律及与复合结构体系的相互作用进行了分析研究,给出了应力波在有软回填层的地下复合圆形结构的介质中传播规律。
The compound structures are of clear superiority in resisting dynamic loading and can absorb more shock energy than ordinary structure. Based on the test results by blasting simulation equipment with diameter of 2.5 m and the calculations by dynamic finite element method, the stress wave propagation in rock mass with underground compound circle structure surrounded by the soft backfill and the interaction between the stress wave and compound structures are studied. The regulations of the stress wave propagation in rock mass with the underground compound structure are obtained.
