混凝土中的爆坑实验研究

Experimental Investigation on Cratering of Concrete

利用爆炸相似理论讨论了固体介质中的相同装药量在不同埋深爆炸情况时的爆坑、炸深与埋深的关系,将传统理论的1/3比例因子修正为1/3.4或1/3.6比例因子。据此设计了混凝土中的炸坑效应缩比实验,并利用某原型实验进行了验证。将实验结果与修正后的比例因子计算值进行了对比,符合较好,其精度可用于工程设计计算。

The cratering of underground explosion as a function of the depth of burst and the charge in solid medium was discussed by using an explosion similarity law.The scaling exponent 1/3 in classic theory was amended to 1/3.4 or 1/3.6. The simulative experiments of cratering effects were designed in concrete, and approved by the real warhead experiments. The experimental results were analyzed and compared with the results obatained by using new scaling exponents, showing that the experimental results accorded with the calculated precision and new scaling exponents can be applied in the calculation of warhead engineering.
