烟囱爆破拆除的切口参数研究

STUDY ON CUT PARAMETERS OF CHIMNEY DEMOLITION BY CONTROLLED BLASTING

在烟囱爆破拆除时 ,爆破切口参数的确定通常都是按经验选取 ,至于参数选取的合理与否却很少深入研究。本文分析研究了切口形状对切角大小和切口高度的影响并建立了相应的数学模型 ,并结合工程实例讨论了切口形状对切角大小和切口高度的影响。

Cut parameters are usually determined by experiences when chimney is demolished by controlled blasting.However,it is rarelyinvestigated whether cut parameters are optimal.In this paper,effect of cut shape on cut angle and cut height is studied and corresponding mathematical models are established.An engineering example is analyzed with the models,and influence of cut shape on cut angle and cut height is discussed in detail.
