摘要
作者分析了爆破切口对砖结构烟囱定向爆破中后坐现象的影响,并根据力学原理建立了砖结构烟囱定向倾倒过程的力学模型。通过理论推导和计算,提出了有效防止定向倾倒发生后坐合理的爆破缺口参数。
The article analyse the recoil phenomenon of towering constructions, which often is caused in directional blasting. And then the mechanical model for it is set up. According to the theoretical calculation, the reasonable range of blasting cut parameter on effective prevention recoil from towering constructions is determinated, and an engineering example is given at last.
