摘要(Abstract):

结合山海关船坞东坞墩爆破工程,介绍了爆破地震波的控制问题。利用增加临空面、采取毫秒延时爆破来降低爆破振动对坞墩、坞墙及周围构(建)筑物的影响,取得了一些经验,望能对类似工程有所借鉴。
Regarding the blasting of Shanhaiguan shipyard east dock pier,the paper discussed the problem of seismic wave control for reducing the influence of demolition vibration on the dock block,the shipyard and other structure by increasing the free face and adopting the millisecond delay blasting.Some valuable experience was obtained in hope to serve as a reference for similar engineering.
