摘要
研究了爆炸地震波的冲击特性。根据实验结果,对质点振动时间历史在强震阶段的不规则变化进行了讨论,发现Fourier谱不能描述强震脉冲作用的特征。研究结果对爆炸地震的结构安全性分析具有一定的指导价值。
The shock characteristic of explosion seismic waves is studied in this work. According to the experimental results, the irregular change of time histories of particle vibration is discussed in the period of strong motion, and it is found that the Fourier spectrum can not describe the shock property of strong motion. The presented result provides a useful theoretical basis for the safety analysis of structures subjected to blasting vibrations.
