摘要
通过数值模拟研究了在相同质量炸药爆炸情况下,对半无限岩石介质地下 10m处拱形工事的毁伤情况。模拟结果得到装药为 2kg,爆源距工事顶端分别为 3m、5m、7m时对工事顶部产生的塌落高度。为炸药爆炸载荷作用与拱形工事防护研究提供依据。
The numerical simulation method was used to study the collapse of arched structures in a 10 m under ground rock medium under condition of same amount of charges.The simulated collapse heigths can be obtained when the distances between explosive sources and upward end of structures are 3 m,5 m and 7 m and the loading charge is 2 kg.The experience can be refered by the similar engineering.
