reduced speed

The magnitude spectra of explosion seismic function reduced velocity potential for two chemical explosions which yield ratio was two, were compared with the ground motion data to obtain that the seismic coupling ratio is approximately equal to two.

应用近场地表记录的其中两次爆炸当量相差一倍的试验数据,比较研究了他们的爆炸震源函数折合速度势振幅谱比,得到他们的地震耦合强度地震矩M0 比值近似等于2,与他们的爆炸当量比值相等,因此得到同爆炸深度的地下爆炸地震强度与爆炸当量成正比的结论。

应用近场(震中距为几公里至几十公里)的地表地运动测试数据来研究爆炸震源特性,将近场地震波传播介质近似为均匀半空间模型,通过去除地表响应,反演了硬岩介质中的地下爆炸震源函数—折合速度势RVP(reducedvelocitypotential),得到了描述地下爆炸震源的折合速度势RVP振幅谱及其参数稳态值Ψ∞、特征频率η、过冲特征量,通过回归分析,得到稳态值Ψ∞和特征频率η与爆炸当量的关系。
