本文假设爆炸冲击波为一种非平稳随机过程,但通过数学上的处理,在去掉趋势项以后,可以认为是平稳Gauss过程.本文先对爆炸波进行频谱分析,然后考虑单自由度理想弹塑性结构的随机响应及浅埋土中结构在随机冲击波作用下的安全概率.根据本文所提出的方法计算可以得出工事在未来的核战争中受核爆炸冲击波作用时处于弹性状态、塑性状态或是破坏状态的概率,用来预测工事的安全性。
This paper assumes that explosion shock waves are a non-stationary stochastic process but can be considered as a stationary Gauss process after removing the trend term. This paper first analyzes the blast wave spectrum and then considers the ideal single-degree-of-freedom elastic-plastic structure. The stochastic response and the probability of safety in shallow buried structures under the action of stochastic shock waves. According to the calculations presented in this paper, it can be concluded that the fortifications are in elastic state, plastic state, or damaged when the nuclear explosion shock wave acts in future nuclear warfare. The probability of the state is used to predict the safety of the fortification.
