本文运用波传播的理论,分析了软弱夹层对爆炸应力波传播的影响,并就入射方波和三角波的情况作了分析和计算。结果表明,任何阶跃波经过软弱夹层均会变缓,尖头波峰值会被削减。两种介质的声阻抗匹配系数对上述变化起着决定性的作用。
In this paper, the theory of wave propagation is used to analyze the influence of soft interlayer on the propagation of explosion stress wave. The incident square wave and triangular wave are analyzed and calculated. The results show that any step-wave through the weak interlayer will slow down, the peak wave crest value will be reduced. The acoustic impedance matching coefficients of the two media play a decisive role in these changes.
