collapse blasting
解釋
拋坍爆破-
This paper discussed the collapse patterns of reinforced frame structures and its mechanism first, and then analyzed the movement stability of construction applying the theory of controlling blasting and dynamic ; after that the lose - stability condition of reinforced frame structures during blasting demolition was studied, a mechanical model of blasting demolition of reinforced frame structure was established ; at last this paper applied abaqus analysis software to reinforced frame structures taking lose - stability as the initial condition
本文首先討論了框架結構建（構）築物的倒塌模式並分析了建（構）築物的倒塌機理，又運用控制爆破原理和動力學理論進行了結構體運動穩定性分析，研究了框架結構建（構）築物爆破拆除的失穩條件，建立了框架結構建（構）築物倒塌的力學模型;並以結構失穩條件為初始條件，運用abaqus軟體對框架結構建（構）築物爆破拆除倒塌過程進行了數值模擬分析。 -
