摘　　要：在倒塌场地狭窄的条件下,采用定向爆破方法成功拆除了一座150 t倒锥形水塔,通过选择合理的爆破参数和起爆方式,实现了水塔瞬间后坐,达到缩小倒塌范围的目的。通过开挖减振沟、铺垫缓冲层等安全防护措施,降低了触地振动和爆破飞石的危害,确保了附近建筑物安全。A practical example of directional blasting demolition of a water tower with a weight of 150 tons in a narrow surrounding was presented, by choosing reasonable blasting parameters and the initiation way,irnplementation of the towers instant recoil, reached the purpose to narrow the scope of the collapse. Through digging the vibration ditch ,foreshadowing the buffer layer of security protection measures, reducing the damage of the touchdown blasting vibration and flying rocks hazards, ensure the safety of nearby buildings.
