| 摘 要： | 现代战争或反恐怖战争中,核电站极有可能遭受精确制导装药的打击。根据核电站安全壳的结构形式,采用Backman和Goldsmith侵彻方面的假设,建立了钢筋混凝土分离式有限元模型,分别对250m/s、400m/s和600m/s着靶速度的弹丸侵彻预应力混凝土结构的过程进行了数值模拟,结果表明:着靶速度对结构的破坏形式和区域有明显的影响,弹丸侵彻表现为明显的冲塞现象。

| Abstract: | In the modern war and anti-terrorism,nuclear power station might be attacked by pinpointed bombs.With Backman,and Goldsmith,s assumpation,separated finite element model of pre-stress reinforced concrete is established.The process of pinpoint bomb penetration into containment is simulated.The result of simulation agrees with that of empirical formula. |

| Keywords: | containment general bomb penetration pre-stressed reinforced concrete numerical simulation |
