摘　　要：以厦门港古雷航道水下炸礁为例,分析了水下钻孔爆破的水击波形成特征,并通过爆破区的水中冲击波压力监测,实测了不同距离处的水击波压力大小和变化规律,研究了水中冲击波压力幅值、正压作用时间等作用特性,得到了水击波传播衰减公式。研究成果对指导工程设计施工和环境安全评估具有参考意义。Taking underwater reef blasting in Gulei sea channel of Xiamen Port as an exam-ple,the forming characteristic of shock wave in water for underwater drilling blasting is ana-lyzed. By field monitoring,the pressure of shock in water for different distances is attained,the major parameter,such as pressure amplitude and positive action time,and the propagation at-tenuation rule of shock in water are researched in this paper. The result can be helpful for engi-neering design and construction and environmental safety assessment.
