| 摘 要： | 随着城市的改造和集中供暖的实现,许多砖烟囱需拆除。结合工程实例,对烟囱折叠爆破进行了研究。分析了折叠爆破的影响因素,对爆破切口的高度和起爆时间差进行了理论探索。理论计算与实际基本相符,对类似的烟囱爆破具有一定的指导意义。

DISCUSSION ON FOLDED BLASTING DEMOLITION OF BRICKED CHIMNEY |
| |
| Abstract: | The implementation of city reconstruction and heating centralization results in the demolition of many of the bricked chimneys.Combining engineering practice,the article discussed the folded blasting in terms of the analysis on its influence factors and theoretical exploration of the height of blasting cut and blasting time difference,with the theoretical calculation results roughly matching the practical case,which could be taken as a guideline in demolition of similar kinds of bricked chimneys. |
