摘要
双曲线结构冷却塔上窄下宽,重心较低,爆破缺口形成后易产生后坐或坐而不倒现象。在阐述冷却塔爆破拆除失稳机理的基础上,结合一工程实例,探讨了爆破切口弧长和切口高度的设计,并对冷却塔爆破拆除过程中的下坐及预防措施提出了自己的看法。
The hyperbolic cooling tower is narrow at top but broad at bottom with lower center of gravity so that recoiling and squatting without collapse often occured in blasting demolition. Combined with an engineering example, the design on the length and height of blasting cut was discussed based on the mechanism of cooling tower demolition instability in this article and also the views on recoil and the preventive measure was given out.
