摘　　要：在南京热电厂180 m钢筋混凝土烟囱爆破拆除时,根据振动速度控制要求采取了减振沟、减振堤坝等措施;并对爆破振动进行了测试,对爆破效果和触地振动进行了分析,对类似电厂烟囱爆破拆除提供了参考。When the 180m reinforeed concrete chimney in Nanjing Thermal Power Plant was demolished by blasting,the vibration reducing ditch and dike were used to control the vibration velocity in request. The blasting vibration was tested and the blast effect and touchdown vibration were analyzed ,which provides reference for blasting demolition of similar chimneys.

关 键 词：爆破拆除 触地振动 振动测试 烟囱
