摘　　要：结合武汉新港阳逻集装箱码头水下钻孔爆破工程,通过现场测试,得出了爆破振动速度衰减经验公式,提出了爆破振动速度安全判据及最大允许药量,针对爆破振动的特征,对实际测得的水下爆破振动信号进行小波包分析,探讨了爆心距对爆破振动信号的影响规律。并依据实测数据评估了水下钻孔爆破对长江大堤的影响,确保了长江大堤的安全。An empirical formula of blasting vibration velocity attenuation is proposed in this paper by field test based on theWuhan Yangluo port underwater drilling blasting project. The safety criteria of the blasting velocity and the max allowed explosive are also achieved. According to the characteristics of the blasting vibration, underwater blasting vibration signal wavelet packet analysis of the actual measurement points out the influence that the blast from the heart of blasting vibration signals. At last, the effection of the underwater drilling blasting is assessed based on measured datas so as to ensure the safety of the Yangtze river levee.
