摘　　要：介绍了内爆炸试验的发展及现状,通过实验研究建立了可以对高能炸药在坑道内爆炸的空气冲击波到时进行预计的公式。该公式适用于爆点在固定横截面的直通道口外、口内及口部处爆炸的情况。利用该公式可以求出空气冲击波在坑道中传播速度的变化。The development of internal detonation experiments is presented. A formula is obtained, which is used to compute the arriving time of the shock wave in the tunnel due to explosions from high explosive charges. This formula is adopted to treat detonations that occur outside, inside, and at the portal of a straight tunnel of constant cross-section, and to compute airblast velocity in tunnel.
