爆破振动信号分析是研究爆破振动特性的重要手段,而实测爆破振动信号往往是多个振派信号的叠加信号,分离出每个振源或特定振源的振动信号对于其振动特性的研究具有重要意义.选取实测的爆破振动信号,进行线性混合得到混合信号,利用独立分量分析(IcA)对混合信号进行分离,获取了与源信号波形基本一致的分离信号,仿真试验表明ICA适合爆破振动信号的分离.
爆破振動信號分析是研究爆破振動特性的重要手段,而實測爆破振動信號往往是多箇振派信號的疊加信號,分離齣每箇振源或特定振源的振動信號對于其振動特性的研究具有重要意義.選取實測的爆破振動信號,進行線性混閤得到混閤信號,利用獨立分量分析(IcA)對混閤信號進行分離,穫取瞭與源信號波形基本一緻的分離信號,倣真試驗錶明ICA適閤爆破振動信號的分離.

Analysis of blasting vibration signal is an important method for studying blasting vibration characteristic-but the monitored signals of blasting vibration usually are aliasing signals of multi-vibration sources,separating the vibration signal of each or special vibration source from the aliasing signal is important to study the characteristic of the vibration source.Some monitored signals of blasting vibration are chosen to linear blending and independent componem analysis(ICA) method is employed to separate the mixed signal;the separating signal is uniform to the origin signal in waveform,which shows ICA method is suitable for separating blasting vibration signals.
