新型钻地武器毁伤与防护计算原理

Calculation Principles of Damage and Protection of New Earth-Penetrating Weapons

目前新型钻地武器对地打击速度普遍在1500 m/s以上,既有地下防护工程设计计算方法无法涵盖上述速度范围。针对当今大口径制导钻地炸弹、高超声速钻地弹、小型钻地核弹毁伤效应与防护工程计算理论存在的难题,简要介绍了作者及团队近些年在该方面的主要理论研究成果。包括:(1)大口径钻地弹弹靶作用弹径效应;(2)钻地爆炸耦合效应;(3)高超声速弹靶作用近区介质流固耦合状态;(4)高超声速撞击成坑耦合地冲击效应;(5)抗钻地核弹防护工程高地应力动静耦合效应;(6)钻地核爆远区深埋防护工程围岩长期稳定性。

At present,the striking speed of new earth-penetrating weapons is generally more than 1500 m/s,which can not be covered by existing calculation and designing methods for underground protection engineering.Innovative theoretical achievements of the author and his team in recent years are briefly described in terms of the difficulties in the calculation theory of engineering protection against large-caliber guided earth-penetrating projectiles,hypervelocity earth-penetrating projectiles and small earth-penetrating nuclear bombs.The major achievements include the caliber effect of the projectile-target interaction of large-caliber projectiles,the coupling effect of penetration and explosion,the state of fluid-structure coupling in the vicinity of hypervelocity impact,the ground shock-cratering coupling effect of the hypervelocity impact,the dynamic and static coupling effect of protection engineering against earth-penetrating nuclear bombs under high in-situ stress,and the long-term stability of surrounding rock of deeply buried protection engineering in the far zone of underground nuclear explosions.
