| 摘 要： | 不同装药结构爆破的地震效应存在较大差异,对于间隔装药结构而言,当采用的间隔介质相同时,采用什么样的间隔方式的降震效果更好呢?对此,就底部间隔、中部间隔还是顶部间隔装药方式的地震效应进行了比较研究.综合比较地震振动幅值、频率和振动持续时间等主要因素,3种间隔方式中,孔底间隔装药结构的爆破地震效应最小,其次为孔上部间隔,再次为孔中部间隔.

| Abstract: | Study and practice show that different interval charge can produce the different blasting seismic effect.However,for the decked charge structure and the same decked medium,what kind of decked fashion can make damping seismic effect is better? The comparison between the different seismic effects caused by bottom,middle and top decked charge structures was investigated in the paper.The particle vibration velocity amplitude,vibration frequency and vibration duration have been compared.The damping seismic effect produced by bottom decked charge was best.Next is that of top decked charge.The damping seismic effect caused by middle decked charge was little. |
