对爆破振动信号进行时频分析是为了更全面而准确地得到信号能量随时间、频率的分布状况。RSPWVD二次型时频分析虽然具有较高的积聚性，对产生的交叉项也有较好的抑制，但不可避免会损失部分信号，无法获得爆破振动信号的细节信息。利用RSPWVD二次型时频分析与小波分析相结合的分析方法对实测的爆破振动信号进行时频分析，结果表明：此种方法提高了爆破振动信号时频特征的精度，展现了爆破振动信号的时频细节信息，可获得更加直观、合理、时频分辨率更高的信号时频特征。

The objective of time-frequency analysis on blasting vibration signal is to obtain the distribution of signal energy with both time and frequencies comprehensively and accurately. The RSPWVD quadratic time-frequency analysis method has high accumulation and can suppress the cross-term preferably, but part signal information will loss inevitably in the process, which induce that the details of blasting vibration signal information can’t be got. RSPWVD quadratic time-frequency analysis method and wavelet analysis method are combined to analyze the blasting vibration signal in this paper, the results show that this method increases the precision of time-frequency characteristics of blasting vibration signal and can obtain its detail information. Employing this method can get more intuitive, reasonable, higher-resolution time-frequency characteristics of signal.
