摘　　要：舟山金海湾2#船坞建成后需要对坞口进行炸礁和围堰拆除爆破开挖航道。本文介绍了该工程的总体施工方案、爆破有害效应的控制标准、爆破技术参数和爆破网路的设计,以及对爆破振动和水击波效应的监测成果。坞口炸礁和围堰拆除爆破取得圆满成功,为类似工程积累了经验。After completion of Shipyard 2^# of Zhoushan Gold Gulf,an engineering of fairway construction by reef blasting and cofferdam demolition blasting was needed for the dock entrance. This paper, regarding the blasting engineering, introduced its overall construction plan, the control standards of basting adverse effects,blasting parameters and the design of bursting network net, as well as the monitoring results of blasting vibration and the effects of water shock wave. The blasting was a very successful one which could offer valuable experience to similar engineering.
