摘　　要：为控制和减少水下钻孔爆破水击波有害效应,研究水下钻孔爆破振动衰减规律,依托贵港二线船闸下游船墩前沿爆破施工区域,开展了水下钻孔爆破数据检测,测试水击波超压峰值、地震波振动数值。由于水击波传播过程中影响因素众多,难以进行精确计算。本文以解决实际工程问题为基本出发点,在研究水下钻孔爆破水击波传播规律的基础上,进行超压峰值传播衰减规律回归计算,综合分析水中冲击波有害效应影响规律。In order to control and reduce the harmful effects of water blast wave during underwater drilling-blast,study its vibration attenuation law,based on the blasting construction area in front of the downstream pier of Guigang second-line ship lock,underwater drilling-blast data are used to test peak over-pressure of water blast wave and seismic wave vibration value.Various factors affecting the transmission of water blast wave cannot be calculated accurately.On the premise of solution to real engineering problems,the transmission law of water blast wave are studied so as to carry out the regression calculation of transmission attenuation law of peak over-pressure,and comprehensively analyze the law of the harmful effects of underwater blast wave.
