摘要(Abstract):
爆破拆除一座 70m高的砖结构烟囱时 ,该烟囱没有按预期的方向倾倒。文中介绍了设计方案、实际爆破参数以及爆破效果 ,并对爆破中烟囱的实际倒塌结果与设计要求不一致的原因作了详细的分析。
When a brick structural chimney with a height of 70 meters was blasted,it collapsed to an undesired direction In this paper,the design scheme,practical blasting parameters and blasting result were presented and the causes for the deviation of practical collapsing result from the desired result were analyzed in detail
