摘　　要：根据阳江核电站爆破振动控制要求,通过试验炮试验、数据剔除、回归和K值修正,确定了允许最大段药量;通过主频统计、代表信号的小波包分析发现:随着比例距离增加,高频成分衰减明显,能量所占频带更加集中。According to the blasting vibration control requirement of Yangjiang Nuclear Power Station, maximum segment charge was given by blasting tests, data removing, regression and K amendment. Statistics of main frequencies and wavelet package analysis of representative signals showed with the increase of scale distance, high frequency components were obviously lost while energy focused on more narrow frequency band.
