摘要(Abstract):
根据混凝土试样在模拟爆振台上的爆振损伤试验,利用声波作为无扰动损伤测试方法,推导了用波速表述的爆振损伤本构方程及动力损伤演化律,理论模型的计算结果与试验结果吻合较好。
Based on the blasting simulating test, the dynamic damage model of the rock is established and for mulated in terms of the wave velosity in this paper. The numerical results from the proposed model are very close to those from the labtest.
