摘要(Abstract):

采用定向爆破拆除了某厂房6联体砖混筒仓,该筒仓立筒相互连接处由钢筋混凝土柱与砖混材料组成且形状不规则。介绍了筒仓爆破切口尺寸计算、复杂结构部位的爆破参数设计和预处理措施。取得了理想的爆破效果,为同类构筑物的爆破拆除提供了参考和依据。
A silo which was made of six joint cylinders with brick-concrete structure was demolished by directional controlled blasting in the plant.Joints among the cylinders were consisted of reinforced concrete columns and brick-concrete materials,moreover,their shape were irregular.Size calculation of blasting cut,blasting parameters design of complicated part,and pretreatment measures were introduced.Good results of blasting have been achieved.The example of blasting demolishing the silo can provide reference for the blasting demolition of the similar buildings.
