摘要(Abstract)：

待爆破拆除的14层办公楼为框架结构,南北长29m、东西宽19m,最高处为46.2m,总建筑面积6000m²。施工过程中采用支撑轴前移的方法,有效地控制了楼体后坐。由于设计了合理的爆破参数,采取了有效的安全防护措施,使爆破拆除达到了预期效果。
Towering 46.2 m at its highest point and covering a construction area of 6000 square meters, the building to be demolished was a 14-storey office building in frame structure with a length of 29 m from north to south and a width of 19 m from east and west.Backlashing phenomenon was effectively controlled by using the method of forwarding back shaft in blasting operation.Thanking to the reasonable blasting parameters cooperated with the safety protection measures,the demolition saw an ideal blasting effect.
