表面异形体遮弹层对防护工程主体毁伤概率的影响

Influence of bursting layer with eroseobject on surface on the damage probability of the main body of protective engineering

有效利用遮弹层以抵抗钻地核弹侵彻与爆炸是地下防护工程防护研究的重要课题。为研究表面异形体遮弹层的抗侵彻能力及对地下防护工程毁伤概率的影响,根据B61-11钻地核弹和由电工陶瓷与RPC球面柱组成的偏航层、RPC为基本层的活性粉末混凝土基表面异形遮弹层的具体参数,分别计算出在700~1000m/s侵彻速度范围内有无遮弹层2种工况下的侵彻深度及防护工程主体破坏效应参数,并进行比较分析。研究认为,考虑极端情况下,表面异形体遮弹层对地下防护工程主体的毁伤概率减小作用为15.99%-39.45%。

The effective use of bursting layer to resist penetration and explosion of earth-penetrating nuclear weapons is an important topic in the research of underground protection engineering.In order to study the anti-penetrating ability of bursting layer with eroseobject on surface and its influence on the damage probability of the underground protective engineering,based on the specific parameters of B61-11 earth-penetrating nuclear weapons and the bursting layer with eroseobject of reactive powder concrete base with the yaw layer composed of electrical ceramics and RPC spherical column,and with RPC as the basic layer,the penetration depth and the damage effect parameters of the main body of the protective engineering are calculated in the range of 700~1000 m/s penetration velocity in two working conditions with/without bursting layer respectively.And then,further comparison and analysis are done.It is considered that under the extreme conditions,the bursting layer with eroseobject on surface can reduce the damage probability of the main body of the underground protective engineering by 15.99%-39.45%.
