爆破振动信号不同频带的能量分布规律
|
摘要
根据爆破振动信号具有明显的持时短、突变快等特点,结合工程爆破地震监测资料,利用小波包分析良好的时频局部化性质,研究了爆破振动信号不同频带的能量分布规律,分析了爆破振动信号的能量在传播过程中随着爆破条件的改变的变化规律。研究结果表明:爆破振动信号的频带能量分布与爆破条件密切相关,其主振频带较宽并可划分为多个子振频带;该方法对综合研究爆破振动危害机理和爆破地震效应,特别是为构建爆破振动速度 频率相关安全准则提供了一种有效的分析技术。
By examining considerable amounts of blast vibration data, which have distinct characteristics of short-duration and abrupt change in signal structure including its spectrum, these characteristics are attributed to typical non-stationary random signal. According to a vast amount of monitoring data from blast engineering, this paper makes full use of the characteristics that wavelet packet analysis has high resolvability and localization, and investigates the laws of energy distribution for blast vibration signals in different bands by wavelet packet analysis technique, some laws are concluded that the energy distribution of blast vibration signal varies with blast conditions during the propagation. The results show that energy distribution for different frequency bands has close relation to blast conditions, and blast vibration signal has wide dominant frequency band that can be divided into many sub-bands. This method is effective for studying the mechanism of blast vibration damage and blast seismic effect in its entirety, specially, for constituting velocity-frequency criteria.
