黄岛热电厂152.8m高烟囱拆除爆破振动测试

对152.8m高烟囱的拆除爆破振动进行了监测,采集到了爆破及烟囱塌落对周围产生的振动数据。经分析得出一些规律性的结论,在烟囱等高耸建筑物的爆破倒塌过程中,装药爆破和切口闭合产生的振动均较小,而烟囱倒塌冲击地面时产生的质点振动是主要因素,因此在烟囱倒塌方向应采取缓冲措施。这些资料可为烟囱等高耸建筑物的爆破拆除设计及对周围环境的影响评估提供参考。

VIBRATION TEST IN BLASTING DEMOLITION OF A 152.8-METER-HIGH CHIMNEY IN HUANGDAO POWER PLANT

The vibration caused by blasting demolition of a 152.8-meter-high chimney was monitored and relevant data were collected. Some conclusions have been reached from the blasting demolition of high building such as chimneys,that the intensity of ground vibration caused by charge explosion and cut collision was usually much lower than that by the collapse impact of high parts to the ground. So cushioning measures should be taken along the direction of the building collapse. The conclusion drawn through data analysis can be referenced by similar demolition blasting.
