摘　　要：阐述两侧紧邻建筑物烟囱的定向爆破拆除。烟囱爆破设计应注意缺口弧长、缺口高度、定向窗、缺口位置及形状、爆破参数、爆破网路设计等方面状况;验算爆破安全方案中的支撑体强度、爆破地震效应、烟囱倒塌所产生的二次振动、爆破空气冲击波、爆破个别飞散物安全距离等相关数据,并对南沙烟囱爆破效果进行分析,从而为其他烟囱爆破设计提供参考。This paper introduces the directional blasting demolition of the chimney adjoining buildings on both sides. Chimney blasting design includes： notch arc length, notch height, directional window, notch location and shape, blasting parameters and blasting network design. Factors such as the strength of the support in the blasting safety scheme, the blasting seismic effect, the secondary vibration caused by the collapse of the chimney, the blasting air shock wave, the safety distance of blasting individual flying objects and so on, are all checked. Finally, the blasting effect of Nansha chimney is analyzed. The experience is worthy of the reference for similar projects.
