摘要

侵彻武器钻入地下爆炸产生的地震波在介质中传播特性较为复杂。针对钻地弹侵入地下爆炸后能量估算问题，基于反映高程差因子的萨道夫斯基修正公式，建立了不同地形状况下地下爆炸震源能量计算模型，并通过震源模型的计算结果得出爆炸能量。实例1对比传统的震源模型（6）与本文的震源模型（12）的计算结果发现该研究所提出的震源模型的精度远高于震源模型（6）；实例2利用该研究的震源模型（13）针对测点不在同一水平面的情况，计算得到的地下爆炸能量结果有较高的精度。计算结果证明将爆炸振动的理论应用于计算钻地武器爆炸能量的方法是可行的。

Abstract

The propagation characteristics of seismic waves caused by underground explosion of penetrating weapons are more complex in the medium.In order to solve the problem of energy estimation after underground explosion of ground penetrating projectile, based on the modified Sadowski formula which reflects the elevation difference factor, the source energy calculation model of underground explosion under different topographic conditions was established in this paper.Then the explosion energy was obtained from the calculation results of the source model.In case 1, comparing the calculation results of the traditional source model (6) and the source model (12) in this paper, it was found that the accuracy of the source model proposed in this paper is much higher than that of the source model (6).In case 2, using the source model (13) in this paper, the calculated underground explosion energy has high accuracy when the measuring point is not in the same horizontal plane.The calculation results show that it is feasible to apply the theory of explosive vibration to calculate the explosion energy of ground penetrating weapons.
