【摘要】 爆破振动效应取决于一次起爆的药量Q、距爆源的距离R、传播的介质以及振动频率F;该文总结了前人对爆破振动效应的研究成果,提出了考虑爆破振动频率的具体办法,发现在不同振动频率范围内,振动衰减规律不同。文章进行了工程实际验算,说明在主频率下,最大质点振动速度是真实的安全判据。更多还原

【Abstract】 Blasting vibration depends on singleshot firing dose Q, explosive distance R, vibration frequency F, as well as the stress wave travelling medium. Based on predecessor’s results, the method of blasting vibration safety criteria frequency is presented in this paper. It is discovered that blasting vibration decrease is different to the different frequency. The maxium particle vibration velorcity(ppv) taking as safety criteria is real.更多还原
