摘要
小当量钻地型核武器,如B61-11和B61-12,已对深地下坚固目标构成严重威胁。基于等效转换技术和地冲击衰减规律,提出了一整套将钻地核爆炸当量转换成封闭爆炸等效当量的计算方法;结合我国封闭核爆炸效应估算方法,获得了不同当量钻地核武器爆炸时的6个破坏分区的具体数据和最小安全防护层厚度,各类方法获得的数值大致接近,说明计算结果是可信的,从而可有效地利用已有的大量地下核爆炸效应试验数据,避免了钻地核爆炸效应研究因缺少数据支撑而陷于窘局;通过计算还得出摧毁200 m深的工程需要300 kt当量钻地爆,而防御300 kt当量钻地爆则需要岩层厚度大于561 m,与外军数据大致相当。
Low-yield equivalent earth-penetration nuclear weapons(EPNW),such as B61-11 and B61-12,have threatened the security of deep underground hard targets.Based on the equivalent conversion technique and the law of ground shock attenuation,a set of calculation methods for converting the equivalent of the EPNW into the equivalent of the closed nuclear burst is proposed.Combined with the estimation method of closed nuclear burst effect in China,the data of six damage zones and minimum safety protective cover thickness of the EPNW with different equivalent are obtained,and the values obtained by various methods are close to each other,indicating that the calculation results are credible,so that large amount of existing experimental data of closed nuclear burst effects can be effectively utilized.In this way,the difficulty that there is few data to assess the burst effects of EPNW is avoided.It is also concluded that the destruction of a 200-meter-deep underground hard targets requires the EPNW with300,000 tons TNT equivalent,while the defense of burst effects of it requires a rock thickness of more than 561 m,which is roughly equal to the data from foreign military.
