端面起爆爆破震动方向性研究
|
摘要
针对爆破中降低爆炸震动效应,保护周边环境的安全问题,运用爆轰和爆轰波传播理论,分析得出:理想一维流动下,条形炸药端面起爆、爆轰正方向的能量比反方向大约32%。通过设计现场爆破试验,将爆炸能量体现到地面结构的震动效应上,又得出一定范围内,等爆心距处、爆轰正方向的振速比反方向大30%,证实了条形炸药端面起爆的爆破震动具有方向性这一特性。
Detonation and detonation wave propagation theories were used in the study of blasting effect decrease and the safety of the surrounding environment.In terms of the ideal one-dimension flow,the energy in the positive direction of the end face blasting of bar-type explosive was 32% larger than that in the negative direction.The field test was designed to represent the explosion energy on the vibration effect on surface structure.The results showed that,in the isometric position of the blasting center,vibration velocity in the positive direction was 30% higher than in the negative direction.The study concluded that blasting vibration bar-type explosive was directive.
